I have gathered some information that I hope you'll find useful.
This list comes from Amy Martin, of Student Advantage Campus Services:

It?s been said that you will DEFINITELY forget your tickets if you
place them in a location designed to help you remember not to forget
We suggest keeping it with your tickets at all times.
You don?t want to end up wearing the same pair of socks the entire trip.
And yet, people do forget to pack this.
The Right Kind of Shoes
Think ahead. What are you traveling to and what is the purpose of
your trip? While sneakers look fine on the plane, you would not want
to be stuck wearing them to a business meeting.
This is especially important if you are traveling overseas. Be sure to
carry currency that will be accepted at your travel destination.
If you are currently taking any prescription medication, we highly
recommend that in addition to bringing the medication itself, you also
take with a copy of the prescription in case you need to get it
refilled while you are traveling.
Important Contact Numbers
Even though you are trying to get away from just about everything,
don't leave your address book/planner at home. Should an emergency
arise, you will need fast access to the person you need to call at
home for help. The last thing that you want to do in an emergency is
have to dig up a number.
You don?t want to neglect your teeth. If nothing else, avoid the
embarrassment of morning breath by ensuring that you?ve packed your
I.D. tags on your baggage
This is perhaps one of the most important things. Baggage I.D. tags
are required. It is a good idea to place I.D. tags on and in your
baggage before you get to the check-in counter. Recognizable tags
assist in locating your luggage upon arrival and assists in returns if
your luggage is accidentally lost."
alt.travel newsgroup: Top Ten Things People Forget When They Travel
"A survey by British travel agency Thomson Holidays... found that one
in five travelers leaves toiletries such as shampoo, toothbrushes and
toothpaste behind. One in 10 forgets to bring shoes, and one in 20
leaves his or her entire suitcase at home...
-- Take Sommer Gentry, a graduate student from Cambridge, Mass. She
constantly forgets to bring disposable razors on her trips. 'I wish
that hotels would offer me a razor instead of 12 useless bottles of
lotion in the bathroom,' she grouses.
-- For Pat Griggs, it's something almost as humiliating as leaving
-- Of all the things Justin Wizard, a writer in Chloe, W.Va., has left
behind, he says his glasses were the most painful. 'My contact lenses
start to hurt after eight hours,' he says. Not having glasses forced
him to keep the dry corrective lenses in his eyes longer. Ouch! But
he's also forgotten to bring his shaver... and toothbrush."
Elliott's Travel Tips for Business Travel: Traveling? Don't forget me
"A survey conducted by Marks & Spencer Financial Services... Whilst
women are more guilty of overpacking, men were likely to forget
holiday essentials. Nearly a quarter of men omit to pack suntan
lotion, compared with 13% of women, while 17% forget their toothbrush.
Arriving in a foreign country without travel insurance is also a
popular mistake with 17% of people 'forgetting' to insure themselves."
This Is Travel: Don't forget your toothbrush
