Paint Question: Should I...

Paint it what you like best. You are going to enjoy it more, and that should offset any minor decrease in value.

For what it's worth, I happen to REALLY like that gold color! My '67 Dart post was that color, but with gold interior. I never got around to it on mine, but I would match the wheels to that color. Matching red might be a little much, unless you are going for the hot rod look. Another thought (and maybe it's just me) is that I find bright colors (and larger wheels) on an A-body make them look smaller.

Does your car even need paint (other than to change color)? It looks very nice in the photos.
