I believe it really depends on the CAI that you buy where the tuner is required. Personally, I'd buy a JLT (i believe they are available for the 4.0s) and a tune with it.
Or a C&L and a tune with it. THAT is actually worth the money.
However with a tuner, maybe it'd be best to wait to put gears and a posi in it and get the tuner/intake along with all of it in one big shot so you aren't have to go back over it again.
All really depends on what you want to do.
If you just want a CAI..maybe a K&N or something.
