The Princeton Review book is good, I believe it's called "Cracking the GRE." I like the writing style of it and all the little tips/tricks. I also recommend you get the official book of practice tests (check the ETS website).
Also on the official GRE website is a FREE software download with 2 practice tests.
Throw in a book for verbal if you'd like and that should be more than enough. At least it was for me.
