@Chase4, you have a good list of achievements. Congratulations!
Since you can afford any school, your list looks fine to me.
You do need at least one, and often two, LORs from teachers in core subjects. You have only mentioned your counselor and a non teacher.
At some schools you will automatically be considered for a scholarship.
Georgia Tech, UWash, UT Austin, Berkeley, UCLA, CMU are all reaches.
Purdue, UIUC, VTech are high targets, could be low reaches for an international student.
For Mech E, Penn State, Ohio State and UMD might be additional schools worth considering. All have very strong Mech E programs and are easier admits than most on your list.
