Pull the shackles off and lube the inside of the bushings where the shackles go through and the shackle pins (the part that goes through the bushing). Not the outside of the bushings where they go into the frame and leaf pack eye. This only applies to the rear bushings on stock leaf packs. But make sure you wait until the truck is sitting on it's own weight before you tighten the front bolts in the forward leaf pack eye. That bushing is like the LCAs up front, if you tighten it with the wheels off the ground it will pre-load that bushing.
DO NOT loosen the LCA bolts. That will create a clunk noise at best. It's tough to get those bolts too tight with hand tools. The mounting tabs are supposed to clamp down on the metal bushing pin very tightly. As mentioned above, just make sure the full weight of the truck is sitting on the ground before they are tightened down or it will pre-load those bushings. It will affect ride quality and bushing life.
And yes, you can get the LCA ball joints separately but no matter how you work it, it's still cheaper and much easier to replace the entire LCA, even if you have a press to replace the ball joints yourself. You can get the LCAs (and the ball joints if you still prefer to do it that way) on rockauto.com for $70 and it doesn't take any special tools to replace them.
