Definitely do the plastics away rotations. Concentrate on getting excellent letters.
Your step 1 score will get you interviews. So definitely apply for the plastic surgery match. Apply to every plastics program. Borrow money, beg, or ebay fire-sale to make it happen.
You can apply to gen surg as a backup. With your scores, I'd say apply to 10-20 gen surg programs as well. Customize your application so your gen surg application has a gen surg essay along with gen surg letters of rec (for gen surg, just finding any surgeon who will write a positive one is enough).
Good luck.
