When I upgraded to 16 inch LT tires, I went with the Bridgestone Duravis. Less expensive than the Michelins and, although I only have 5K miles on them, no problems so far. As mentioned above, just be sure you have enough clearance all the way around, including taking suspension travel into account.
Also, I had to adjust my WDH because the LT tires are around 1 inch bigger in diameter, which was just enough to require adjustment on my setup. Yours may not need it but something to check after you put the new wheels on.
As for wheels, I bought Ultra Type 62's from Tirerack. A big benefit of using Tirerack is that mounting and balancing is free if you buy the tires from them; you still have to pay for shipping.
