If you're going to have a roommate, wait until you know some contact info so you can collaborate on who will bring what, regarding things like t.v., DVD player, fridge, etc. Those are all expensive, bulky things. In a small space, better only to have one.
I also got a small folding ironing board that I could put under my bed - cost about $7 at Dollar General, I think. Esp. if you're going to sew it would be useful. DO try to take along your sewing machine. I wish I'd had one when I was in college, but up to that point I'd always just borrowed my mom's.
