Google "MotorolaOneClickRoot_psouza4" to find the one click file download site. I think that the one click installs the Superuser, because I never have gone to the market to download it in person, but I have lately had updates to it from the market. The market seems to be the source it. Clockworks, I am not familiar with but I bet it is in the market as well. I use D2bootstrapper, and think that is what you refer to as clockworks.
