Tintinalli and Rosens are both great books, but I really like Harwood-Nuss' Clinical Practice of Emergency Medicine. Each topic is basically broken down into 2 pages of what you've gotta know and the part that sets it apart from the other 2 major books is that it includes disposition decision making pearls and classic pitfalls associated with each topic (ie not differentiating AAA from renal colic in a 75 yo with flank pain-and help with who can go home who needs to stay) I find it a lot easier to read quickly, though not as dense in physiology.
PEPID is also a huge help...ask around and see if your residency has put together a group discount or see if you can...i know one of our faculty arranged a big discount after talking to someone at one of the conferences. it's a great software package for your palm including just about everything you need for EM with references and a good pharmacopea/interaction/etc package
most importantly rest a few more days...you won't know what hit you July 1 whatever you do now...try and read a little every day when you get started but do something that keeps you sane too..(sometimes you have to sacrifice reading when the 2 are at odds)
