It is no fun being anxious. Fortunately, even top Internal Medicine programs tend to look at your clinical grades, research experience, awards, etc. rather than focus solely on your Step I score.
Your Step 1 board score may prevent you from getting interviews at the super competitive programs (e.g. UCSF, BWH, MGH, Duke, etc.) ...but taking Step 2 CK early is a great idea and because you have done well in your clinical rotations, you will probably do well on the exam. With a good Step 2 score, I predict that you have no problems getting interviews from most of the other programs you have listed.
(When I interviewed at UW, my interviewer told me that they love to take their own students and students who have rotated there and done well. If you are really interested in UW, I recommend that you do a rotation there.)
Fortunately, there are MANY wonderful IM programs and the "top tier" programs are arguable (you'll find many a thread about them!)...it sounds like you have a strong application. Worry just enough to do well on Step 2.
Also: the SDN search will lead you to more questions like your OP...and more responses that will allay your anxiety.
Good luck to you!
