I bought the PORSCHE trunk lettering from Suncoast Porsche in Florida. It is actually the factory lettering from the Panamera sedan, so I'm sure you can order this from any Porsche dealership. The badge on the back of the newer Cayenne's are probably the same thing too.

As for the center voids left behind the bumper, the other concern I'd have is that the left side induction cowl also protects the two audible horns from rain water/water from car washing. If water hits those horns, they can malfunction, so be careful to not spray water on them directly when you wash the car.
