2" lift kit is must if you plan to venture off-road with your Jeep, it will even help more in your Jeep Wrangler Unlimited case due to its long wheel base. So for sure it's worth every penny to get lift-kit. Now which one is good, I am not really sure in Jeep / Mopar world may be someone more knowledgeable here can advise further.
For Light bar, there is two school of thoughts: For people fan of beam opt for halogen spot light setup. For people who like flood opt for LED light bar. If you go LED light bar, my highest recommendation is to go for CREE LED light bar, as they are VERY bright and helps a lot in the night . I am using CREE (top) and non CREE (bumper)LED bars in my Pajero (first car) and know the difference very well. I can read the dunes formation from 250 - 300 meters with my top mounted CREE LED light bar.
