I have the same year YJ 4.0L that's on it's third suspension, now an RE
4.5". With a 4" lift you need to install a quality slip yoke eliminator kit,
it's really the only way to get rid of the driveline vibes. When I ran 33s,
and before I swapped out my stock axles for Dynatrac units, I regeared to
4.10s and liked it a lot. 4.56s are a bit much with 33s.

Re: What gearing?
Most prefer 4.56 with 33" tires and the 4.0L. If you have a 5-speed and
do alot of highway driving, 4.10 works well. If available, 4.27 might be
nice. Do the math for what you have now and see how each would compare:

http://www.quiknet.com/~ke6vut/gearchart.html
As an alternative to pricey new gears, consider used 4.10s from salvaged
4-cylinder Jeeps.
Lowering your t-case will not necessarily cure vibes. The slope of your
slip yoke and that of the rear pinion must be parallel. You can use
shims under your rear leaf springs to point the pinion either up or down
as required to make these slopes equal. But, with a short wheel base and
4" over stock, it's likely that the relative angle of the rear shaft
between these two slopes will be greater than 15 degrees in which case a
tail shaft conversion and double cardan shaft are required:
