Also, just to pick up on Ronin's list - a mousemat is essential.
Both at home and at uni I just use the wooden surface of my desk, but the desks at the i-series are not smooth and varnished, and it's horrible to play anything on, even things which don't require fast mouse movements. They do sell mousemats there, but they sell out fast and are fairly expensive from what I remember of last year.
Moral is, if you don't normally use a mousemat, you'll need to find and bring one, and possibly start playing on it now to get used to the sensitivity changes etc (I spent my first day at i34 just adjusting to the new speed, which was a waste).
