Woh, slow down there... you don't need to be going out and buying books yet. Wait and see what they're going to require (a book list is available during the late summer) and also, buy what you think is appropriate for your learning. I like to buy all the books because I like to have references for the future, but it's a personal thing.
The books we used are as follows:
Gross Anatomy: Moore and Dailey's Clinically Oriented Anatomy
(I and most other people find Chung's BRS review extremely helpful) Atlases are your choice--Rohen and Netter were my picks, though Clemente is also good
Embryology: Larsen's Human Embryology
Histology: Ross's Histology Text and Atlas
Biochemistry: Marks, Marks, and Smith's Basic Medical Biochemistry
Pharmacology: Katzung's Basic and Clinical Pharmacology ( I recommend the Lippincott's Illustrated Reviews book to simplify)
Physiology: Berne and Levy (the professor never really followed this book...it was pretty much a waste, though PhD's claim it's excellent)
Pathology: Robbins' Pathological Basis of Disease (Ed. Cotran, Kumar, Collins)
Microbiology: Murray's Medical Microbiology (good for reference, but it wasn't really needed-I've heard there are better Micro books-for review see Clinical Micro Made Ridiculously Simple)
OMM: DiGiovanna's An Osteopathic Approach to Diagnosis and Treatment
Again, don't start buying the books, and don't start studying before you get to school. You're not going to need all the information in the books anyway, and they're pretty much there for a reference to the powerpoint presentation (there are exceptions). Enjoy the time before school...don't waste it studying. I didn't have any time off at all between finishing my masters and starting school, and I regret it...take it easy before the "fun" begins.
As for the computer use during lecture, it depends on the lecturer. If they're a good lecturer, the students will put the powerpoints up on the computers and follow along. If not, the students will play games, check e-mails, surf, etc... I try for the most part to follow along out of respect for the professor, but sometimes it's just bad and boring, and you need something else to keep you occupied. Also, I've used the computer to type notes during class, especially during anatomy (no powerpoints). It's a personal thing.
Good luck
