Question before I order my new suspension

had a thread going that seemingly lost its steam. Just have a few quick questions before purchasing my new suspension. It's my first IFS lift and my first time swapping leaf springs. (front and rear coils on the TJ wrangler I owned previously are my experience)

Replacing my suspension with a heavier duty option to help with towing and hauling, but am trying to minimize "lift".

I decided on 5100s front and rear as a good pair to go with the general spring hds. I'd go with 4600s but the pre settling height of the hd leaf springs seem to demand the 5100s. Also the 5100s give me flexible options for the future and are 20% off making them pretty much the same price as 4600s.

Before ordering though I'm trying to figure out what else I will need besides the
General spring hds
Front bilstein 5100s
Rear bilstien 5100s

I'll be pressed for time when my
Order arrives so I CANNOT have to wait for more parts.

I'd call if it wasn't Sunday, and many places are closed tomorrow so please help.

From my research and inspection of my suspension it seems I should replace my coil springs too. There are tons of options out there but all seem to be for 2.5-3 inches lift. What should I go with?

Also what other hidden purchases do I need? Bushings? U bolts? Diff drop if I'm setting the 5100s on the lowest possible setting to still keep factory rake? Anything else
