Our system is a bit different (systems based, so no single "path" block) -- but I studied from big Robbins, a little bit of Goljan audio and Robbins review. I loved big Robbins -- reading it through gave me a great overview and it has tons of the epidemiology that helps with figuring out the question (e.g. 6:1 M:F ratio, mostly presents 20s-30s -- your question stem is not going to be a 52 YOWF with a new case). Also, for Cards, Lily (sp?) is an absolute must-have.
We also have access medicine at my school, which has a lot of online textbooks you can use (some are better than others). These are good supplements on a subject-by-subject basis.
YMMV -- I think that I probably would have done equally well if I had just used some of the RR material and stayed away from Robbins, because a lot of my tests were very much "bullet point" based. That said, I studied a lot of material that was not covered in our classes (and got some flak about it from the few people with whom I study), but I felt it was important to learn the material even if it wasn't covered in class. I was able to cover all of the material I considered important (even what was glossed over in class) and give due diligence to the material emphasized in class without it being overwhelming. I did very well on our lecture exams and (hopefully) am in a good position for Step 1.
I think the poster above who said "different study styles" hit the nail on the head. I can't memorize to save my life, because my brain just turns off when I read one of the super-outliney bullet point texts -- it's like trying to memorize arbitrary lists of information to me. That said, if I read a broad background of the material, I can often reason my way to the right answer without knowing the specific point about which the question is asking.
