As Emily said, every college can give you a bursary if you get a maintenance grant, as that is university based.
Lots of colleges give travel grants as well. I got £400 from King's to go to France for a few days, for example.
As for book grants, I've heard Trinity are pretty generous, but I've never had to buy a book anyway so I'm not sure how useful I would have found a book grant. College libraries can often order books in for you, and you have the UL and faculty libraries as well.
