Thanks for the detailed pictures! I was able to get everything taken apart, and fixed the read error I was having after a couple of readjustments.
One important note: the lens screw should be turned counter-clockwise, not clockwise. A quarter turn is also likely to be too much; better to adjust a few degrees at a time and test repeatedly until the right setting is found.
gameFAQs.com has a lens calibration guide, with notes on how to reassemble the GameCube for testing without screwing everything back together.
I also agree that steps 11-17 can be skipped, as well as step 5 to remove the controller ports.
Agreed, it should be counter-clockwise.
