Highly recommend to read before school starts:
"From Novice to Expert" by Patricia Benner. Explains the stages of development of a nurse. Knowing where you are and why the faculty is taking the approach they are, especially in the beginning, is more than a comfort, it will show you how to get the most out of your studies.
Recommended to have available before school starts:
Few things are as frustrating as writing those APA-formatted papers. Some folks will tell you to buy the APA style manual. Well, for the formatting part, I bought a Word template at http://www.perrla.com/
and that fixed most of my problems (had to tweak slightly as needed when printing a paper), then to win arguments with the instructors, I used the manual in the library. No need to buy the book.
"Writing Literature Reviews" by Jose L. Galvan (now up to the 3rd Ed), on the other hand, is simply awesome. Being able to format papers is one thing; having something to say, and saying it cogently, is another. I wish I'd had this book from the beginning.
Knowing the names of muscles and bones was never much of a priority in my school (I never touched my Mosby muscles and bones study deck). But if you spend some online time reading up on how the different chemical circuits of the endocrine system work, or how circulation works (including maternal-fetal and newborn circulation), that review will pay off.
