i cand help you with the DS and the SYE, but with the lift ill let you know some things.
being that you are from NY like myself, i dont care what year you have, your going to have seized everything. First things first, get like 3-4 bottles of PB blaster or liquid wrench or things of the sort (de-seizers)
the front end wont be too bad, if everything is PB'd not much should break especially since you have a newer model. but the rear is what really holds the build up. have a sawzall and a torch ready. the front side leaf bolts will most likely be frozen in the box. you may have to cut and/or torch them out. the rear bolts will be a 50/50, and i think the RE kit comes with 3.5" springs and a shackle, if so, be prepared to have a fussy top shackle bolt.
i hope they come with brake lines, because your going to need them at 4.5"
the only thing about the front is getting the front end to push up far enough to bolt up the control arms, a lot of times that front axle is kind of resistant about going into the right places... pretty much get every jack, jack stand, clamp, tool, everything you can find, youll probably need.
like i said though, if you do not have a torch, sawzall or angle grinder, you might want to think of getting one of each. (note: by torch i dont mean welder, i mean a propane canister with a torch top, but a welder might come in handy if you have to cut into anything)
Good luck, hope it works out!!
