Very nice work! My jimmy will be that color.
As far as a bumper I have had great luck with this one

I have bought 2 of them and they are rechromed originals with USA chrome. You have to order them when they have them, they run out frequently. Make sure you get this number GMK4143000672A
They also have rechromed rear bumpers
