It depends on what kind of place you'll be staying in. Thankfully, I never lived in a dorm (always suite-style) residences, so I didn't really bother bringing things like flip flops and so on since we had private bathrooms. If you are using a common bathroom, I'd probably bring a pair of cheap flip flops, a decent bathrobe and some type of basket-thingie to carry your toiletries in. Also, bring more towels than you think you need, that way you can toss them in the washer when you've got 4 or 5 to wash, instead of 1 or 2.
Bring headphones if you have roommates in your room, and even if you don't, still bring headphones. It's just common courtesy.
If there are snacks or foods that you don't think you can get at college, bring a few with you. It's a little thing but I found it really helpful to have some of that home type of stuff with me.
I would also always take more pairs of underwear and socks than any person really needs (we're talking like 20 of each or more), because I hate running half empty washers and my rez always had the huge industrial sized washers, so this let me accumulate a good 2-3 weeks of laundry before things turned desperate. Heh.
Most of all, have a great time! Roommates are an adjustment, but I've met some wonderful people that way and if you're flexible as a person, you can deal with most people. And really make the best of your orientation week - go to all the events, do all the things. You will meet tons of fellow students that way and have an awesome time. I kind of cringe at the thought of my law school o-week last year but it was absolutely fun and I can't wait to join in this year. Free food, free booze, new friends and old ones you haven't seen for a summer - what more can you ask for?
