I would wait to use Uword until you start organ systems. If you need a Qbank for basic sciences, use Rx or Kaplan. Uworld integrates all the basic science into organ systems and would not be all that helpful for the most part.
Instead of the review books, I would recommend trying to read as much of the "real" books as possible, especially when you start organ systems. Instead of BRS physiology, use the real deal--Costanzo text. Pathoma is fine but if you have time to read Goljan or Robbins, do it. The more you can deeply understand and solidify during your actual courses, the better off you will be on step. There will be plenty of time for the review books later on, when you've actually learned the material. The review books are more like a study guide to help refresh your memory on what you already learned. This is much less important in basic sciences than in organ systems, but the same principles apply.
