What you need to do first is figure out what else, if anything, you plan on adding to your rig like a winch, rear bumper, roof top tent, sleeping platform in the back, etc etc, and then match a suspension set-up for the extra weight you've added and the lift you want.
If you get your front level, your rear will be sagging every time you load it down for a trip. Many guys like me choose to have a positive rake (rear higher than the front) so you can load down the back cargo area and not be sagging in the rear.
Getting your suspension right is a little trial and error and it's quite common for guys to choose one set-up and then switch something out pretty soon afterward because the set-up didn't work out as planned. With my suspension set-up, I quickly realized the rear springs I got weren't anywhere close to what I needed to support the weight I carry.
Anyway, I hope this helps.
