Rebuilding front and rear suspension

I'm looking to thoroughly get my suspension up to snuff. Rear suspension sags, front wanders when going over bumps, and overall ride quality and handling is lacking, in addition to general squeakiness.
Here is my plan:
New shocks all around
New bushings all around
Thicker torsion bars
New leaf springs
Looking for your guy's thoughts on this, specific parts, additional upgrades

Would a sway bars be a worthy upgrade? Need to save some dough for the brakes.
If you're going to run modern radials, consider the Moog Offset upper control arm bushings, allows for more caster than stock, stock was bias ply tires

The Skosh Chart is a beginning reference point for alignment

A post in another thread, said
That for the type of driving most of us do, the factory style bushings will be fine.I agree.

Sway bars, yes the factory were either 13/16 or 7/8 ??

Leaf springs, yes

Great shocks, big difference but $$$
