Welcome!
As for adding bluetooth, the cheapest thing to do, is buy a sunvisor bluetooth setup, it's about the size of a Garage door opener. About 20-30 bucks. As for adding a factory setup...not sure.
As for the USB port for the iPhone/iPod use, not sure that it will work. I have seen mixed results when useing IPods and Chrysler Mygig/Ucconect radio systems.
