I like the basic idea Klingon gave. Not sure on the titles cause i thought guardians, sentinals, counslers, etc were different 'classes' of Jedi, sort of a different focus not something you progressed through. but the rise as a jedi, turn to the darkside, redemption and ultimatly to a spirit idea i like.
also, as far as the Jedi go (moviewise), i thought that the trials were to become a master, not to go from Padawan to Knight. but then when do you go from Padawan to Knight if thats the case...im confused
