2" lift is generally considered a little small for 33s, but I believe there are a number of members that do so just fine every day. It all comes down to what you want to do. Offroad? Probably want a bigger lift, as a little flex will kill your fenders with 33s and a 2" lift. If you stay on the asphalt, I think you'd be fine with 2" and 33s.
As to the spacers, again, I dont doubt it would fit. Is it optimal for off roading, probably not, but maybe thats not what you intend to do with it. Its your jeep, after all :-).
