In general, prep and a clearcoat are what separates an excellent job from an amateur one. I haven t painted interior plastic or vinyl pieces yet but I d suggest that you use a paint and wax remover FIRST, to clean oil and armoral off as both will prevent good adhesion (amoral is silicone-based and will cause dimples in your paint job! - it is a bodyshops worst nightmare). THEN sand with 320, 400,600. I find wet sanding works best, although it requires wet-specific paper. I believe there are plastic-specific primers that are supposed to improve adhesion and flex a little-maybe a bumper cover product. You could spray-bomb the colour but I d urge you to clearcoat it (if you want shine) with a catalyzed paint. This makes it so much more durable and the shine will last forever-little nicks won t produce chips then, either. Anything out of a spray can won t be as tough. A bodyshop won t charge much and the finish will exude quality. A catalyzed clearcoat can be wet-sanded , polished and waxed too-that s show-car quality!Either way, have fun!

PS 200 grit (220) is quite coarse for plastic and would work best if you want to remove a surface pattern that s molded into it.
