Don't forget the body-to-frame bushings. I was astounded at the difference body bushings made on my El Camino--and that was AFTER rebuilding front and rear suspension.

Properly greased, properly installed, the Polyurethane will outlast rubber and give you more-precise handling in the process.

"Sitting perfectly level" probably just means that all the springs have worn evenly.
This is your project, not mine...but if I were selecting parts it would get stiffer, shorter springs all around. Same--or perhaps higher--ride height, but with more-responsive handling and higher load-carrying capacity.
