easiest way to adjust the cam bolts

Be vewey,vewey caweful with the antiseize.
If you get on the face of the bushings or under the cams, it has to come off, or else it will be possible for the cams to slip, and your alignment has to be redone. The absolute only place to put that stuff is on the shank of the adjuster bolt, and only enough to prevent rust.
If you unbolt the UCA from the car, and reinstall the adjuster bolts (No nuts) into the arm, they should spin freely. If you then reinstall the bolts with cams, correctly indexed,into the frame sockets(no UCAs), and with nuts finger tight; then they should rotate semi-freely with a wrench. But if you fail to install the loose cam-plate correctly indexed, then it all locks up. But you would really have to try hard to assemble it this way with the UCA installed.This was mentioned in post #2.
Be advised that Many of us have run into a situation with new MOOG adjuster bolts. It seems that the unthreaded shank is a hair long, preventing a solid clamp by the alignment tech. Sometimes just a spin around the block is enough to cause the alignment to slip.I cured the problem by installing 1/8" hardened washers under the heads of the cam-bolts.
