2.5 is a great starter kit. Your rubi already comes with mono tube shocks and they fair very well. Theres a lot of great kits out there so take your time and choose your poison wisely. Don't skimp out.
Budget Boost (leveling kit)... if your not planning to add aftermarket bumpers/winches...weight. with that said, start doing research for a coil lift if you plan on adding weight.
Since its for your wife, and she uses it daily... i would suggest all terrains since the mt's will take a hit on mpg, and loud. rule of thumb...stay light with tires. an additional 10lbs of weight to ur current setup per wheel will equate to 100lbs in load.
Longevity... look into the toyo at2 (65k, or 50k) or falken wild peaks (50k)
do some research on duratracs, toyo open country at2, hankook dynapro, and cooper discoverer. all these tires are highly reputable in the jk community. good luck
