Advice for COMLEX III

I just registered for COMLEX III next month. I am a general surgery intern, and have had the majority of my non-surgical rotations. I just bought crush step 3 and the NMS q book. Anyone have any advice for studying (length of time, books, important topics, etc) What about the new computer format and how many questions do you need to pass?
