Dashboard, Plastic interior repair, etc?

[Jaybee]

Hey TR! I just bought a 1992 Subaru Legacy Sedan L. It's in pretty beat up condition, and needs some TLC. The interior is one of my biggest concerns, there is plastic parts missing and dings in the Dashboard, Arm Rests, and other plastics on the inside of the car. My question is, how would I go about repairing this myself at home for cheap? Is there some kind of filler I can use, or an adhesive?
I really want to start making it look nice, it has a lot of work that needs to be done & I want to start with the simple things.
Any help would be greatly appreciated!
Also, I need a good site for finding parts for my car. It's pretty old, so it's been difficult finding parts at local junk yards or automotive shops.
