I have to agree with KSMI and J Dub. Don't start studying so intensely right now. You will burn out. Heck, I had a three month study plan and still had to take a break somewhere in there. Just take it easy until March/April. Also, if you are in school really think about if you are going to have time to devote to the MCAT in April/May when finals start getting crazy. Is there a particular reason you have July in mind?
As for the other questions. No one can tell you what you need to focus on other than yourself. It all depends on what your weaknesses are. You probably will need other materials other than the free stuff. I used the entire ExamKrackers series as well as The Berkeley Review books. I had the Kaplan books they use in class as well, but honestly, did not find them to be all that helpful.
