I'm not sure I can help with the axle spring question but after just installing and driving on Sumo springs (assist springs) I would suggest that you look into that at the same time if you have the funds.
I would also recommend that you check into an "assist" spring. Much easier to install.

...the sway bar bushings can absolutely cause that noise! When installing new bushings, there is lubrication that is applied between the bar and the bushing. If that lube is dried up, it will creak like crazy when the bar is flexed! Depending on how old your rig is, I might also consider replacing the OEM bushings with the newer poly bushings front and rear. That's not a hard or expensive job to do in the driveway! You can find the poly bushings on Ebay, front and rear for around $75.
Excellent suggestion ! If you are getting a lot of sway, it might be time for new shocks.
