the lift height itself should be good for 33s, but you may rub for other reasons, like backspacing. but if you're going to run 33s on 5" i'd definately recommend LCA's front and rear. uppers you could probably do without. but lowers would adjust your pinion angle, and center the axles under the wheel wells. i'm actually doing the opposite of you right now, i have a 2" bb, and i'm adding 3.5" coils, right now i have front adjustables and a rear trackbar but i'm holding off until i get rear adjustibles and kevins track bar conversion for the front.
someone with experience will chime in, but i've heard nothing but bad stuff about the track bar relocation brackets. i hear they break easily. and not just on zj's, but they're generally junk all around, do yourself a favor and do it right.
