I have used this site for packing tips before:
http://www.packinglight.net/plight/text_1.asp?tx_id=90&
It offers tips on how to pack a lot of items into a very small place.
I use Eagle Creek Pack-It folders when we travel a lot. You fold the items carefully, put them into the folders, velcro the folders closed, and they stay relatively unwrinkled during the trip. They are also available at packinglight.net.
Good luck, and have a safe trip.
