Well Krylon makes a type of paint called Fusion for plastic that would work for your panels. Then for the cloth parts you should be able to remove the ones in the doors and redo them with a cloth of your choice. You can get molded carpet for the floor. Seats you can either get your redone which costs a bit, or you could put in racing seats, or swap seats from a different car such as S2000 etc. Its up to you waht you want to do. Personally you have to ask yourself if the car is worth it. If the outside and motor are in really good shape and it runs nice then it might be worth fixing up, but if the car is falling apart then look for a newer car to play with.
