All you really need for a surgical clerkship and for the shelf is Surgical Recall and an abundance of questions (e.g., Pretest or Appleton & Lange Review of Surgery). Pretest questions are generally poorly written but the explanations are excellent. A&L's questions are a little better, a little on the easy side however, and the explanations are horrible.
Mont Reid is a little dense for the shelf, and its format is tough to digest. Do you go around memorizing laundry lists all day? If you do, you can do Mont Reid.
Lawrence is good and not dense. Easy read. It's not as well organized as other books on its level though.
As far as the bigger books like Schwartz, Sabiston, et al., I haven't really taken a look through them and don't plan to until residency (if I ever get there).
