Skip the exhaust spacers, buy a front driveshaft. At 2.5 inches it isn't necessarily needed provide you don't get too much droop. If you do go with a new front driveshaft, you will need front lower control arms. I would go with 17 inch rims and tires, more tire options and more likely to find tires in stock at tire shops. Skip the adjustable track bar. Depending on how much lift you actually get, you may need a drag link flip up front which would address the trackbar. In the rear, I would buy something like the EVO rear track bar bracket. You can run 35s on factory carrier, just make sure it has isolators or whatever to make sure it's tight against the tailgate.
The MT/AT debate just depends on what terrain you want to wheel.
Full circle clip axle shafts are good. Along with the outer gussets.
You could run something like a budget boost and clear 35s.
