At some universities, you can purchase a moving in pack consisting of bed linen, kitchen equipment etc, which you can collect on arrival. This is generally used by overseas students, but is available to anyone, and should be reasonably priced.
I would avoid going overboard on clothes. Just take some basics and use accessories to change your look. Quite apart from the difficulties of transporting your entire wardrobe, you don't get a huge amount of storage space in most rooms.
