Howdy from Washington! I'm a stick man myself so I'll leave the questions up to those who know better than me. It's best that you put your location up in the right top corner, never know which board member could be close by and it makes trading parts easier. Do you know if you have the stock 4sp transmission in it now? If so it should be a SM420, it's popular with the 4x4 rock crawlers because its strong & low geared. Whatever parts you take off become good trading material, so add to your list a single brake pedal setup. Also you might consider better brake hardware, a booster, power brakes, or disks up front.
