Your academic accomplishments are excellent and you should be quite proud of them. They alone should be good enough to get you into any of the schools you listed. Your overcoming of adversity will also benefit you at many of the schools. The big weakness i see is that none of your Extracurricular activities demonstrate any form of leadership and very little in the form of excellence (the trombone being the exception).
I would suspect that this will make your top four schools,
UC Los Angeles
UC Berkeley
Cornell University
University of Michigan (Ann Arbor)
somewhat of a challenge.
Good luck!
