Your plan sounds about right.
Remember–grades always come first. Concentrate of earning the best grades you can. ECs can always be added later. Drop volunteering if it interferes with your grades.
Because you will be taking many pre-reqs at a CC before transferring, med schools will want to see that you take higher level electives in bio & chemistry at your 4 year college. If your transfer programs allows it, take Ochem at the 4 year college.
RE: scribing. Companies will train you, but they will also require you to take a skills test to get hired. (Most want you to be able to type at certain speed w/ high accuracy, have good spelling, and have some basic computer operating skills. Some may require a knowledge of basic medical terminology.)
