Usually to get top dollar out of a Vette, you keep it original. That being said, if you want to change exterior color, put a black interior in it. That would be code 19V vinyl or 192 leather. A black interior goes with any exterior color.
To strip the paint I would suggest sanding with a DA. I start with 40 grit to remove the clear and some color. Next sand the color off with 80 grit. Finally sand the primer off with 120 grit. This will leave you with a good surface to do your body work and epoxy prime.
I haven't used paint stripper on Vettes for over 20 years, just too many negatives. It's a hazardous waste, will cause the seam lines to shrink later (ask me how I know), not recommended by GM, extremely messy, etc.
