Your list seems reasonable.
I would comment that from reading your "Brief Profile" you seem light on the clinical experience that med schools expect, if volunteering at the school for autistic children is your only clinical exposure. Do either of your other health-related ECs provide you with face-to-face time with sick people? Or are you planning on additional shadowing, job, or other volunteerism to demonstrate a broader experience?
Your stats, research, and leadership all look good.
