I have the exact kit with different shocks. I added a 1" coil spacer front and rear on top of the 2.5" coils, and I was still fine with just the components included in the 2.5" coil lift. If you didn't have a rubicon I would have also suggested getting some jks quicker disconnects.

 

I also have the Teraflex 2.5 inch with Teraflex shocks and added 3/4 inch daystar spacers to each corner to level it out since my 12 unlimited Rubicon is a little on the heavy side with AEV front and rear bumpers and AEV tire carrier and 9.5 CTI Warn winch. Four Wheel parts did my lift build and i told them to build it and include the components that i needed so that i would not have any problems down the line. They said the drive shaft was not needed but they did put on a JKS adjustable front track bar, Skyjacker SS( they first put on a Bilstein SS but they said that made the jeep pull left) and Teraflex exhaust spacer. I am also running Pro Comp 35x12.5x17 Xtreme AT tires with 17 inch Pro Comp wheels. They also gave me a three year warranty on my set up. I do not do any rock climbing at all, too much money invested in it to purposely tear it up and its my daily driver. I do trails, mudding and hunting in it. Mine drives and tracks real well and does well off road also. Your set up seems to be good but of course you can break anything if you abuse it enough. I would suggest you talk to an expert shop about your build such as a shop that does lots of jeeps and they can steer you the right way. Thats what i did.
