adding to what sidharthsp already said, I think you should go thru Halliday and Resnick from cover to cover and then add to the major topics (like Mechanics, Modern, QM, E&M, Thermo) with some more advanced readings as you follow the list of possible topics for the PGRE on the ETS site. As far the more advanced readings go, you don't have to cover the entire texts, just the topics from the ETS list and especially the ones that were either not covered at all in Halliday & Resnick or just barely skimmed over.
Covering some Solid State - just the basic stuff from the first 3-4 chapters of Kittel as well as some superconductivity - would be a good idea too but don't dwell too much on it as there won't be that much of it on the test anyway.
Also, with the more advanced books, don;t waste time with trying to remember complex derivations or extensive solutions to complex problems, this is true especially for QM and Thermo.
There are some lists of books here with suggested books on this site, personally, I went with what I had used in my undergrad classes - Symon (ClassMech), Bernstein (modern), Griffiths (QM), Reif (Thermo) and some of Kittel (Solid State) - basically, go with the ones you feel comfortable with.
Only exception I made was for E&M - I had used Wangsness but for PGre prep went with Griffiths because 1) it's a better and more approachable text and 2) Griffiths is big fish in the group that makes up the problems for the PGre exams and a lot of problems on the test feel as if they were taken stariaght out of his books ... same goes for the Halliday and Resnick Foundations of Physics, btw.
It won't hurt to cover something on lab and experimental techniques including basic error/statistical analysis.
Of course the 4 tests are a fundamental part of the whole prep so you should leave yourself at least a month, better two, before the test date to go thru them and see where you have gaps in your prep and spend some extra time on those specific areas. Cover these tests extensively and make sure you feel comfortable with the problems and the time constraints because as you will find out, time-management during the actual test is just as important as good knowledge of basic physics.
It might be a good idea to actually cover 1 or 2 tests at the start of your preparation just to give yourself an idea of how quickly you need to solve the problems and how deep you will have to go when going thru those books above.
Also start early and try to be done with the bulk of your prep over the summer 'cause if you are gonna be at school come test time, you will find yourself in hell
