I assume I would also have to get the 3.5TMAP then as well?

Hi there,
You don't have to swap the headers but I recommend it as they have a better flow rate. turbos are a straight swap. You will indeed need to mount your MAF sensor somewhere if you're getting rid of the 5.0 air box.
You can keep the 5.0 air box, it will fit over everything but since you are doing the conversion I would change to a cone filter setup. Your'e problem will be that you will need to relocation your MAF sensors.
