A) here is the right link sorry; http://forum.bodybuilding.com/showthread.php?t=998224
B) I do have starting strength, and maybe I just missed it, but Rippetoe doesnt really go into deep detail about adding assistance work, he just mentions it.
C) In the write up, it talks about why it is so important to have a coach for power cleans. He also mentions how Rippetoe, in both Practical Programming for Strength Training and in Starting Strength (ed. II), says that without a coach or at least some expierence in the lift, power cleans shouldnt be attempted, but subbed for pullups/chinups and/or rows.
