The plastic and metal parts should cover with paint just fine after a good cleaning and de-greaser, and possibly a light sanding with wet/dry. Prime and paint. The vinyl parts I would not recommend painting, but you didn't mention that, so I will assume you are replacing with your new color.
I am still needing one set of rear gold seatbelts and buckles, along with other misc. gold trim. So if you are interested in parting with some of your old items, please let me know.
