Those are big questions!    Certainly too big for me to answer directly.
Perhaps we can get to specific items that I can answer if you find a 
case that works for something related to what you want to do, and then
ask about details of converting it to do what you really want.

For your case, perhaps the "c13_pocket" test suite case would do as a start.

Then, for info about features that are currently supported in mesa, you should scan
the files "star_defaults" and "run_star_defaults" in mesa/star/public.
You'll find sections on overshooting, opacities, and winds.
You'll also find controls related to brunt frequencies and ways
to output FGONG files for use in getting pulsation modes.

Good luck,
Bill
