Get yourself a copy of Costanzo's Physiology book. It is well written, concise and seems to get to the main points. Boron and Boulpaep is a waste - You're going to be a doctor not a physiologist (unless you're an MD/PhD I suppose). Plus when you begin to study for Step 1 you'll almost invariably be using BRS Physiology, which is also by Costanzo and appears to be her textbook condensed down to the bare-bones physio you need when you're reviewing. Read this book (the big one, not the BRS one) along with your modules starting 2nd semester. I don't think you'll get any use out of it until then.
Read the recommended readings in Robbin's as you have your path lectures. Although its dense as hell you may be surprised how it can add to your understanding of pathology. At the very least you should at least skim thru the pertinent sections and make sure you spend time looking at the pics because this is where all the path pics you see on your tests will come from.
Buy Clinical Microbiology Made Ridiculously simple and read about the pertinent bugs as your classes go along (theres also some micro pharm in here which is good too). This is an extremely weak subject at UB and unfortunately for us its important!!
Thats all I can think of right now, but I'll update later probably
