If you plan to drive it and the lean and worn suspension doesn't bother you- don't worry about it. If you want a modern ride with independent front suspension and modern shocks -,invest in the upgrade, or invest in air ride technology like you indicated - and don't worry about the cost. If you want a tighter but true original look and feel -,go with new springs, shackles, and king pins (for steering and tracking assist). Or just replace the old style shocks with modern shocks and new springs etc for a lower budget upgrade.
The lean on the left or, drivers side could also be due to normal spring wear over time - that is fairly normal for the driver side to have that. But 2.5 inches could mean other things like broken springs, and shackle parts, or a combination of all.
