tx2001xj

So I have the Medium Load OME leaf springs (ARB-CS033RB) installed on my 2001 XJ. I'm looking to upgrade the coil springs in the front to the OME ZJ ones (2934's) here in a couple weeks.

From my research, here are the other parts I'll need to level out around 3 or 3.5 inches:

Shocks
Adj Track Bar
Coil Isolators

I either want OME or Bilstein shocks.

Would it be best to get the longer Bilsteins (Bilstein 33-066868 46mm and Bilstein 24-188197 46mm) OR the shorter Bilsteins (Bilstein (24-185622) 46mm andBilstein 24-185639 46mm)? Or would I be better of paying the extra 30 bucks per shock to get the OME ones?

Also, is there anything else I'll need? T-case drop? As of now, my XJ is a pavement prince unfortunately... So I want something that will still keep the ride quality as good as possible. Thanks for any help.
