Lift kit and dual rate springs?

I have a 2014 stealth and I just got all my heavy accessories bolted up and as expected the rear is sagging severely. I added an inch of preload to the rear springs to get me to 13 1/2" front and 13" of rear ground clearance which I’m ok with for now, but I know I’m going to give up some ride quality. I’ve read tons of threads and decided I eventually want racertech springs, a rubber down 2 1/2" lift and to disconnect the sway bar. I basically have 2 questions…
1) Are the springs and the lift compatible?
2) If you could only buy 1 at a time, which would you do first?

I would like to have around 15" of ground clearance and a reasonably plush ride at slow speeds. I mostly trail ride with a little mud thrown in.

Thanks in advance
