My plan is as follows:
FA and Step Up (borrowed from our library)
BRS for BHS, Path, Physiology and Biochem (secondary to FA)
Clinical Micro made ridiculously simple
Lippincott and FA for Pharm
High Yield and FA for Neuro and Gross
Cell Bio, Histo, and Embryology can suck it
I'm also planning on taking the two NBME usmle assessment exams, as well as purchasing 1 month o' QBank.
I've heard that Kaplan has some great review books, but I'm not looking to spend much more money. Plus, the review texts I have (above) work for me.
As for the OP's most recent question, I don't know what to tell you. I've talked with quite a few people who have taken the Step recently and they have ALL recommended the books I've outlined above, and nothing more. Working plenty of practice questions is good for you too.
