A dry erase board for your door. It will be very helpful when your friends are trying to find you. A couple of plates, bowls, cups and silverware. Perhaps a few small pots or pans, but don't over do it. Your college's kitchen has other utensils, but it's nice to have some things available in your room.
Plastic crates to store the above-mentioned cooking supplies, books, or acquired junk.
However, your college does have a computer lab, so there will be computers available. These people are Rice students who also work for User Services, and they know their stuff. If you live in a quad, you will have a common living room with plenty of space for furniture like a couch, coffee table, floor lamps, rugs, and chairs. Upperclassmen will sell this stuff cheaply, and there is a Target extremely close by. I hope this has been helpful for you.
