Welcome to the site!!! i too have a 74 but it's a Ventura model. I am in the same boat as you as far as finding out which wheels/paint will look the best. It's not easy. I can't see pics yet but will check when I get home.
I love my Pontiacs, I just got a 455 that I bartered body work for. Just need to save up some more rebuild it and mate it up to a t-56. The goal is to look stock under the hood, no shinny chrome. The body is kinda be stock, I am keeping the door handles, but I shaved the marker light and am going to shirnk the bumpers in. I am going to order my rims soon just so I have them, damn 12 week build.
