What you propose sounds a bit excessive and expensive for what you"ll be using it for. If your new TJ Wrangler is your DD, I'd think about a more middle of the road mod that's probably more road friendly but also capable offroad. I don't know about your lady, but my wife just barely tolorates the additional 3 inches it takes to get her butt into the passenger seat of my Wrangler.
Lot's of good options out there, but personally I don't think a 5" long arm suspention system would be the way to go for a DD. Check out what others on the forum have and some more research. Good Luck and welcome to WF!
