Front suspension upgrade questions for first get with firestone ride rite airbags

Hi all, so the goal id like to accomplish is getting a steel front bumper ~120lbs on the taco..

Due to the weight I carry in the bed (campershell, sleeping platform, general storage,, overlanding stuffs ect.)
I have installed a set of firestone ride rite airbags (as an aid to the leafsprings). I also mistakenly purchased the 2" spacer pucks for the airbags because I thought they were required for the stock suspension (they are not, and have since been removed). My ride is seem slightly lower in the front but much better than when the pucks were in.

Now im looking to upgrade the front suspension to accommodate a steel bumper, along with the higher load ive been carrying.. ive been doing a bit of reading and ive been drawn to the old man emu either 881, 882 or 883.. im still trying to work out the differences and what would work with and not fight the air bags in the rear..

I would also like to add those 2"spacer pucks back and lift the truck 2" although I have no idea what that would entail as far as additional parts goes.. or what the best options would be..

Other notes,
I avidly offroad but would also like to keep things highway friendly, while balancing off-road capabilities.

Part numbers for stuff and things,
Firestone ride rite airbags: 2304 (installed)
2" Spacer pucks: 2366
Old man emu suspension: 2881, 2882, 2883

Let me know if you have any questions, ill answer them as best as I can. I appreciate the help in advance. I can also work on pictures if that'll help.
