Honestly without seeing it we don't know if there's anything we'd change. If it was me buying it I would upgrade it to some 40's, and change from a 5speed to an auto.
The final decision is going to have to rest with you, but there is a lot of money in parts in that rig and odds are it's been built well. I've hardly ever seen a dirtly built rig that is running 500 a piece coilovers on each corner.
The electric fan is going to give some of the HP back to the 4cyl and the 5.13's along with 4:1 TCase gearing will give you a pretty darn good crawl ratio. Then throw the 14 and 60 on top of that and if you need to hammer down the pedal to get up or thru something you won't have to worry too much about breaking things.
