You'll need to fill out your profile so we can know what is done to your Jeep.
You'll need a certain pump, depending on your motor, because the ones with the reservoirs attached won't fit a 2.5 MPFI.
You need :
Pump (either with reservoir or without) [2.5 MPFI needs a remote reservoir]
Power steering gear box
Power Steering pitman arm
New drive belt that accommodates the PS Pulley
I believe that's it. I purchased a pump/lines/gearbox/pitman arm for 120+shipping of eBay. I'm waiting anxiously for it to show up...then I'll grab a reservoir and tackle this job.
