dash looks great! was the toothpaste for the lens?
On the brakes, I think it's a win, win....I am not much help as I have the same debate because discs on the rear look great with big rims, but the modulars/bigger fronts look great also....
As far as braking performance, I really don't think you'll notice a huge upgrade with the discs on the rear....even many high dollar modern trucks use drum rears since most of the braking pressure is (and needs to be) at the front anyways....
