If you already have 30" tires, why the rush to lift it? Why not just install rock rails and see how it performs? Then decide what the rig's shortcomings are and address those. Why the hurry to throw money at it?
Here's the big secret that nobody told you. You are going spend WAY more money on your Jeep in the long run than you ever imagined. There's even the likelihood you may need to sell it in the future because it it's a huge money pit.
I'm trying to get you to wait and think about why you want to do all this. In the long run, having a good plan and doing it right, ONE TIME, is the cheapest way.
