Geen bearing install

I really tried to spare all you guys from yet ANOTHER newb question, but running a search didn't get me what I need.
Changing out the center section tomorrow and also putting in the infamous Green bearings.
Problem is, they came with no instruction whatsoever and I'm not sure exactly how the install should go.
What am I tearing out and what should stay. The new bearings look straight forward....press on the bearing then the retainer, but what about the old axle preload adjusment stuff?
If 'ya know of any printed instructions on the web, please guide me there. If not maybe one of you could splain the process to me? I've used a press to put on bearings before, but not Mopar and certainly nothing like these Green bearings.

Have mercy on me for I know not what the heck I'm doin'.
