For the headlights, if you are feeling up for it, yes, you can take the bumper off and then swap the ballasts from driver to passenger and see if the problem follows. If it does, you know it's the ballast. If not, it's the whole assembly.
Checkout Hawks Motorsports. Then grab a lot of salvaged camaros. They may have one
