there i a lot of info on that topic at <a href="http://www.usmle.net/step1" target="_blank">www.usmle.net/step1</a>
it is a message board and those kaplan 3 volume lecture notes seem to be really popular. it covers every subject and the notes are in outline form with a lot of diagrams and pictures. most people don't think the anatomy section is that great, so they usually recommend High Yield for gross, neuro, and embryo. that and a lot of people supplement path with BRS or Goljan. hope this helps.
