Been there done that! I had a red interior and hated it, almost sold the car cause of it a long time ago. I gutted the car and replaced it with my own creation of black and gray. I was able to get parts out of a few donor cars, but for the stuff I couldn't get I painted.
What ever you do don't buy the vynal/interior paint from the auto stores. Sure they will work and look good, but it won't last long. Theres a company called SEM paints, their paint is excelent! You can get it at auto detailing shops. Its kinda pricey, but worth it. You will also have to take the extra time to prep the parts that are in need of paint. The best cleaner I found was Maxi-Clean. You can get that at the detailing shops too. If you have any other questions
e-mail me.
