Avoid the Princeton guide to advanced physics, it will be no help for the GRE, even though it's a decent book for grad study.
There are a lot of great quantum books, mechanics books, e&m books, etc. But 85% of the stuff on the physics gre is right out of a good undergrad book like Serway. That's the one I recommend, just work as many problems in there as possible.
Another excellent book if you don't mind the occassional typo is Browne's Physics for Engineering and Science, in the Schaum's series. It's even better than Serway if you don't have a lot of time because he gets right to the heart of the matter and doesn't use too many words. It's a nice cheap book too. He writes good problems and then solves them.
