To the OP, if you do bedline the bottom, I would suggest getting rid of the side molding. From what I've heard, chrome bumpers take a LOT of prep work to get anything to stick to the surface well, but I've never done it myself. Parts are so cheap and easy to find for these trucks, you could probably get yourself a primered smoothie bumper for the same price you could sell your stock one for.
Of course, if it was me, I'd pull the trim, get a paintable grille and front smoothie, and keep the two tone look going up front. Light teal on the grille and pewter for the bumper, but that's just my opinion. It would obviously cost a little more too.
