Wheels that chromed are just a little too flashy for my taste (then again, all my cars have been covered in duct tape, so anything that's been washed is more flashy than I'm comfortable with).

As for the new bumper, it works better with a Land Cruiser than shiny wheels, but at the same time, it might make you look a little too much like a paranoid survivalist. That's more your call.

At the same time, it's an attractive vehicle, in a nicely understated way, so do you really need to do anything to it?
