Hello peterp,
After quite a lot of reading and a good many interruptions, I believe
I have your situation explained.
I've had a look at your site, and was unable to find anything there
that might cause you to be dropped from the index altogether. Your
problem is actually quite benign!
You're suffering the effects of both changing your URL in the past
month, and the current Google Dance. Neither of these are anything to
worry about, they'll shake themselves out in due course.
First, let's explain the Google Dance - the affectionate nickname
given to the period each month in which Google updates the index.
During the Google Dance, page rankings and standings can shift wildly
or disappear altogether in a matter of days, hours or even minutes as
new pages found are added, dead links are discarded, and content
changes are considered.
James Kendall at SEO Today explains the Google Dance:
"The Google Dance
Google has at least four different indexes that are manipulated to
test different results when the Google Dance is on. During the dance
you can get a glimpse of how your site ranks in their different
indexes. If you do a search in the default Google index around the
time of an update, and then do the same search in one of the other
indexes, you will get different results. For example, on February 22
you could have gone to http://www2.google.com/ to preview the new
Google index and compared the current listing (www.google.com) to next
month's (www2.google.com).
The time surrounding Google's updates is normally referred to as the
Google Dance because the databases are switched around and back a
couple of times before things become stable."

"What is the Google Dance?
Once a month, and totally unanounced, Google has a major shift in
it's rankings. This is when Google "tweaks" is algorithm, and when it
updates each sites PageRank and Back Links.
During the month there will be minor changes in rankings. This is
called 'Everflux'. But only about once per month does Google Dance,
updating the back links and the PageRank. The dance usually lasts
about 3-5 days. During these days the Google Results will vary
widely."

"The best time to put new pages online is during the Google-Dance. If
you let too much time lapse between the completion of the update, and
the publication of new content, you may reduce the amount of new
content that will be included in the next update."
Google Update - The Google Dance
http://www.linktree.info/googleupdate.php
"The name "Google Dance" is often used to describe the index update of
the Google search engine. Google's index update occurs on average once
per month. It can be identified by significant movement in search
results and especially by Google's cache of all indexed pages
reflecting the status of Google's last spidering. But the update does
not proceed as a switch from one index to another at one point in
time. In fact, it takes several days to complete the index update.
During this period, the old and the new index alternate on
www.google.com. At an early stage, the results from the new index
occur sporadically. But later on, they appear more frequently. Google
dances."

There's even a nifty cool tool, called the Google Dance Machine, that
lets you see if Google is indeed doing the WWW Boogie:

This is why you're seeing such wildly changing results - Google has
its dancing shoes on and is sorting out and building the new index.
This is completely normal (if a bit nerve-wracking for the
unsuspecting webmaster!), and occurs approximately every four weeks.
Now let's address the rest of your query.
The reason your new pages aren't showing up in the index yet is
because...well, they're new! The Googlebot hasn't found your new
links yet, so your new pages aren't going to show up in the index
until it does.
Here's how it works, starting with Page Rank, and progressing through
getting indexed and what happens when you change your URL:
" PageRank relies on the uniquely democratic nature of the web by
using its vast link structure as an indicator of an individual page's
value. In essence, Google interprets a link from page A to page B as a
vote, by page A, for page B. But, Google looks at more than the sheer
volume of votes, or links a page receives; it also analyzes the page
that casts the vote. Votes cast by pages that are themselves
"important" weigh more heavily and help to make other pages
"important."
Important, high-quality sites receive a higher PageRank, which Google
remembers each time it conducts a search. Of course, important pages
mean nothing to you if they don't match your query. So, Google
combines PageRank with sophisticated text-matching techniques to find
pages that are both important and relevant to your search. Google goes
far beyond the number of times a term appears on a page and examines
all aspects of the page's content (and the content of the pages
linking to it) to determine if it's a good match for your query."
PageRank Explained

"We update our index every four weeks. Each time we update our
database of web pages, our index invariably shifts: We find new sites,
we lose some sites, and sites ranking may change. Your rank naturally
will be affected by changes in the ranking of other sites. You can be
assured that no one at Google has hand adjusted the results to boost
the ranking of a site. Google's order of results is automatically
determined by several factors, including our PageRank algorithm.
Please check out our "Why Use Google" page for more information on how
this works.
You may want to check and see if the number of other sites linking
to your URL has changed. This is the single biggest factor in
determining what sites are indexed by Google, as we find most pages
when our robots crawl the web and jump from page to page via
hyperlinks. To find out who links to your site, use Google's link:
tool."
Google Information for Webmasters - Why does my page's rank keep
changing?
://www.google.com/webmasters/4.html
"Google finds sites through a process known as "crawling" the web.
This involves robot software that follows hyperlinks from site to
site. Google currently looks at more than 3 billion URL's during the
crawl. The process may take several weeks to complete.
When a URL is submitted to Google, we look for it in our next crawl.
If you've already submitted your URL, your site could easily appear in
our new index, which will go up when the current crawl is completed.
However, if no other site links to yours, it may be difficult for our
crawler to find you. Conversely, if many sites link to your page,
there is a good chance we will find you without your submitting your
URL."

"If we have not picked up your site and it has been several months,
then it is likely that our spiders are not able to find your site. If
you increase the links pointing to the page, Google will likely find
your site in the future."
Getting Listed
://www.google.com/webmasters/1.html#B1
"We cannot manually change your listed address at the exact time you
move to your new site. There are steps you can take to make sure that
your transition goes smoothly, however. Google listings are based in
part on our ability to find your site by following links from other
web pages. To preserve your ranking, you will want to inform any sites
that currently link to your pages of your change of address. As long
as the links change as you move your site over to a new location, your
PageRank should not be adversely affected.
If your site goes unlisted for a time, this does not mean you were
intentionally dropped from our index. Sometimes in these transitions,
we fail to find a site at its new address. Just be sure that others
are linking to you and we should pick you up on our next web crawl."

Notice the mention of links in the last section. Leaving aside the
fact that your new URL is new, your new URL doesn't have anyone
linking to it yet.
Have a look:
http://www.6sigma.us/default.asp shows 116 links pointing to it:
Google Search Results: link:http://www.6sigma.us/default.asp
://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=utf-8&newwindow=1&q=link%3AOrYKbOWQLGkJ%3Awww.6sigma.us%2Fdefault.asp
http://www.6sigma.us/default.html, on the other hand, shows no links
pointing to it yet:

http://www.6sigma.us reveals 116 links pointing back to it:

://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=utf-8&newwindow=1&q=link:OrYKbOWQLGkJ:www.6sigma.us/
At the moment, your best option is simply patience and "change of
address forms" - let those who've linked to the old page know that
you've changed your URL and ask them to update their links accordingly
so the Googlebot will be able to find your pages more easily on its
next crawl.
In the meantime, issue the Googlebot an invitation for a visit -
re-submit your URL here:
For Site Owners: Submit your site
://www.google.com/addurl.html
...and hang in there. Once the Googlebot has the current links to
jump to, you should see an improvement as early as the next Google
Dance (about 4 weeks hence).
While you're waiting for things to sort themselves out - and they
will! - why not have a look at some of the resources available for
