They will provide the books for you(or at least they used to). There is a list of all the books available to you available with the testing information. You should be able to find it by searching their website. Realistically, they probably won't be that much help if you have studied. When I took the test, I think that I may have looked up 2 or 3 things in the CFR's and that is it.
There is also a member here who teaches the classes and he might have the list on hand.
