A 2.5 lift would be fine. I wouldn't do a Rough Country lift tho at any height other than their puck lift maybe. Look for the "most popular lift on WF" post and get drop brackets option. The brackets will help the steering and handling of your Jeep. I believe our vendor AOR sells the lift and everything as a package deal for a good price. Driveshaft will go sooner on a 2.5 lift than zero lift, but will not be an immediate issue. And it will give you warning before it goes - vibrations, grease, torn boot. So just periodically check it. Shouldn't need a steering stabilizer.
Nittos are heavy, not the most daily driver friendly tire. Nor are 35s for that matter.
With the 3.8 engine, you may want to strongly consider regearing with 35 inch Nittos.
Big Jeeps are a pay to play sport. Don't compromise with a cheap lift. Wait until you can do it right. Perhaps if budget is an issue, a better option would be a puck lift.
