I don't know about your university specifically, but this is for general information.
If you are travelling by car, you can bring more things.
Things you would typically need to bring:
- a few sets of clothes/shoes/etc.
- bedding (pillow, mattress, covers, sheets)
- towels and toiletries
- some cookware (a few pans), plates.bowls, cutlery
- laptop
- stationery
In your accommodation, there isn't a lot there, just the essentials. In your room, there would be furniture (desk, wardrobe, bed). In your kitchen, you might have a kettle, microwave and toaster. You can always double check when you have your accommodation confirmed.
In terms of books, I would go to Amazon or Ebay as you can usually get a good discount. You could also look on Facebook groups of your course to see if older students are selling their textbooks second hand. Have you been given a reading list?
