oooo no one has addressed what to take with you!
ALWAYS have: a hammer, nails (like, 1/2 " and 1 1/2"), pliers, duct tape, and saftey pins
not only will you find a million reasons whiy you need them, it's also a REALLY good way to make friends because everyone needs the said items at some point!
also, if you are a guy, then you'll be ok with the roommate thing as long as you lay down the law about darkness/quiet and people in the room. if you're a girl, well... i'd suggest getting to know your roommie first a little bit, then say something like "it's so great that you're such a nice person to live with! why don't we get some coffee/order pizza/eat lunch together in the caf and talk about the best way to live together?" this is what i WISH i had said to my college roommate my freshman year. (i'm a woman, BTW- no prejudice or anything but guys seem to get along a lot better than girls roomming together)
take along plenty of cool stuff to go on the walls- put up pictures of trips you've taken, your family, your dog, your car etc. when people come in they feel more attracted to you as a person if you have interesting things on the walls with cool stories behind them rather than the stereotypical pot leaf/ marylin manson/ greenpeace poster. try to put up things that seem interesting but that don't offer a chance to immediately label you as one type of person (ie- if they see a pot leaf poster, then they're gonna automatically peg you for a pothead- which will drive away most of the people you'd actually get anything out of talking to)
also, don't hole up in your dorm room. go to the library, go to all the freshman/incoming student activities (if there are any) eat in the caf as much as possible, go to student functions. look people in the eye and smile! living in the dorms is a great way to meet people who will help you out later in life. i actually have met really cool people just wandering around all the dorm buildings at my campus and sticking my head into all the doors that were open just to meet the people inside
good luck!
