For myself I really like the Maroon/Champagne two-tone. You are going to want a white back ground for your decals so the side window area would be best left white or even a clear window. I think it might be easier to make your two-tone if you leave the Bel Air side trim. You mentioned removing the tail gate trim. I did this last year on a custom Nomad build. You will want to get a cold beverage and several sanding sticks, it will take a while. That would make the Nomad a little more commercial looking with the trim gone. If you're going with a more custom look you might want to remove the V-8 emblems below the tail lights also.
