Do I have the parts correct for my lift kit and what is the difference between front and rear height

Mopar or Moog is fine.

Polybush is also available, but I have never used it on KJ.

In general, using these bushings that do not easily deform elastically will result in quicker steering and increased vibration.
However, since rotational resistance is reduced, suspension movement becomes smoother.

is any one of those going to be better value/quality than the others, or are they all about the same?

I don't know if there are differences in rubber bushings depending on the manufacturer or distributor.
It's been a year since I switched to Moog's and I haven't had any problems.
I'm just concerned about the red rust on the outer sleeve.

Ok, I don't think rust is a huge worry, suspension tends to do that because it's so exposed
