Definately free the lower control arm from the shocks, sway bar, and steering knuckle. With the lower control arm bolts loosened, the arm should rotate enough to almost touch the ground!

Edit: Disconnect both sway bar end links to rotate the sway bar down and out of the way. It will probably be easier to disconnect the upper ball joint only, leaving the steering knuckle with tie rod connected to the lower control arm. Use a jack to relieve pressure on the shock and remove the upper shock mount bolt. Now the lower control arm should pivot down enough to reassemble the torsion bar, key, and retainer by hand - if not, loosen the rear lower control arm bolt and remove the sway bar completely to access and loosen the front lower control arm bolt - now it should rotate down enough for easy reassembly.

You will need to jack the lower control arm back into position to reattach the ball joint and shock. After reassembling and torqueing all bolts (except sway bar), you can adjust the torsion bar while front end is still in the air. Then drop the truck to the ground and reattach the sway bar and end links. Finally, get an alignment performed.
