Sup Kane 007 and welcome to the forums. Congrats on your new ride. If you are planning on getting new wheels you might as well get aftermarket 19 or 20 inch wheels. I just switched from 19 inch f sports to aftermarket 20 inch wheels and the ride is still great (something I was very concerned about)! My point is if you are going to go through the trouble might as well make it different than OEM wheels, even they are not bad looking.
As far as reprogramming, you might have answered your own question. With new wheels you might s well get new TMPS sensors, which will need to be reprogrammed. Wheel places charge 20-40$ for this, or else your psi will show as "--" on the dash for each wheel.
one last thing, with new wheels you might need a pair of rear camber adjusment arms, made by SPC, those will set you back about 250-300$. Kind of sucks that between tmps sensors and camber arms ure looking at about 500$ alone, thats without new tires and wheels but boy are they worth it!
hope this helps and happy hunting
