Yes, in the front the OME HD springs and struts will take place of the ~2" lift.

For the rear the JBA 4" springs will just about level out your vehicle with the loads you carry (OME rear springs will need help).

Shocks depend on budget..... IMO the best overall shock is the adjustable FOX, but they're expensive. The next best is a properly valved 2.0 Emulsion shock (probably 60/80 if you're carrying that much weight, 40/80 to go a bit softer). Next step down would be a 255/70 valved Bilstein... a few options there including resi's.
