Anatomy - Netter's Atlas of Anatomy, Rohen's (invaluable IMHO), Acland videos, and UMich anatomy website for questions
Biochem - BRS, Lippincott, and/or Rapid Review (BRS and Lippincott are good for review questions, especially Lippincott).
Phys - BRS (aka Skinny Linda), Costanzo Physiology (aka Fat Linda), and Guyton and Hall review/question book; some people highly recommend Dr. Najeeb videos, but I never used them. Kaplan videos are also good for supplementation.
Neuro anatomy - Haines atlas
Micro - Sketchy Micro (online video subscription); Clinical Microbiology Made Ridiculously Simple was the go to before Sketchy and is still a decent source if you don't mesh with Sketchy.
Embryology - High Yield Embryo or BRS. I discovered the Kaplan videos while studying for step, wish I would've known about them 1st year.
Immunology - Abbas; a lot of people also recommend How the Immune System Works
Path - Pathoma or Goljan Rapid Review (I used both and they're both good, but ultimately I preferred Pathoma and dropped Goljan) and Robbins Review of Path for questions.
Pharm - Sketchy Medical and/or Kaplan pharm videos along with pharm sections at the end of each organ system chapter in FA. I preferred Kaplan pharm videos.
Histo/Histo path - If you feel you need a resource for these I'd recommend Netter's Atlas of Histology for histo and Robbin's Atlas of Path for gross/histo path.
Clinical stuff - Bates is definitely worth getting if you don't like relying on the internet to figure stuff out. For preclinical my school's attitude was to follow Bates to a T - if you didn't you lost points. So if your school recommends a different text I'd get that instead; but I'm definitely of the camp that feels getting whatever is recommended for clinical medicine/physical exam is probably worth it in the long run.
UpToDate is awesome if your school has a PBL type curriculum and you have to do presentations or group discussions.
For practice questions in general - I'm not sure what the PreTest series is like for pre-clinical topics, but for shelf exams they tend to be highly regarded and may be worth checking-out for pre-clinical exams.
