Marketing Research for Educational Software

I am in the process of starting a home based personal business dealing
in software sales and web revenues. Before investing large sums of
money, I would like to research the market, in order to gain
comprehensive information, of the various factors involved.

The two areas of interest are:
1.	Educational & Personal hobby software; and
2.	Setting up a web site, which will produce its own revenues as well
as a base for advertising and facilitation of my developed  software.

These topics will be discussed in depth.

The goal of my question is not necessarily the answers to my
questions, but to who will be the best provider(s)/source(s) at the
lowest cost for the information.

REGARDING THE COMMENT TO MY PREVIOUS QUESTION:
http://answers.google.com/answers/threadview?id=297703

Therefore, in phrasing the third question, you may
instead wish to ask for online references and links to
business-planning resources that you can use to train yourself on how
to write an effective business plan, rather than ask for the business
or marketing plan itself.

THIS IS WAS I HAD IN MIND
