Bring a sock to put over the door. That's the universal sign for "I'm getting some. Crash in the lounge tonight."
Your school's website should have something like a "Student Life" page that has a list of things to bring and, more importantly, NOT to bring. For example, when I was at Buffalo, space heaters, microwaves, hot plates, toaster ovens, and sterno burners (or any type of open flame, including incense or candles, although most RA's looked the other way on this) were not allowed in your room. They had a communal kitchen on each floor that had microwaves and stove/ovens. You COULD bring a little fridge, though. Most schools should have their dorm rooms wired for high-speed internet, so bring your comp. if you want. Buffalo's rooms were wired for cable, too.
The general rule of thumb is if you wouldn't put it in your bedroom back home (except the fridge), you shouldn't bring it to the dorms, and anything that could be a potential fire hazard is not allowed. Here's Buffalo's student life handbook in PDF format to provide a guideline but remember your school may be different. Go to your school's orientation, this information will undoubtedly be passed out the first day.
