Seems like your questions have been answered but I have ARB deluxe bumper with 10k winch, Metaltech sliders, Asfir skids, Prinsu roof rack, and ValleyTech rear bumper with dual swing outs, rotopax and a 34" MT spare currently my truck weighs 6600lb. I'm still on AHC and I wheel regularly. I added King springs in the rear before I added the rear bumper and skids but I didnt need it as my pressures were still in spec. The only thing I had to do was adjust the torsion bars.
As bad as I want a fixed lift to have the lifted look its really no need for it. In my opinion I would save your money for now, skip the lift, flush your AHC fluid and replace your shock bushings if they havent been recently and get your bumper, winch, protection etc.
