I would personally go back to stock hangers and a flip kit for the adjustability. Especially since you plan to notch and tub. Ive heard a lot of mixed reviews on drop leafs. Some say they are bouncy and some dont seem to have a problem with them. The way i see it is, you are already wanting to go lower. Once youve gone with drop leafs, you will be maxed out on drop in the rear. If you wanna go lower, youll have to go back to stock hangers and leafs and a flip kit then. Youd be better off just going straight to a flip kit/stock hangers now so you can be 6"/7"/8"/9"/10" or whatever you want in the rear.
As for shocks your budget will determine the "best" solution. I would say, if you can swing it, to go with a nicer fox/qa1 etc.
