Welcome to the forum. Are you any closer to getting a Tacoma as of joining?
Lots of good first mod recommendations already. Wheels and tires (and lift) do make the truck look nice, but rock sliders are very important if you will be taking the truck off-road. I didn't have sliders and first and damaged my rocker panel pretty hard. The truck will be capable as it is stock, but sliders will prevent any damage if you do wheel it.
