I haven't found much in writing either, but heard a few things on Brulosophy podcasts that I've incorporated that seem to work. Here is pretty much everything I know about kegging:
1) After cleaning, and also checking all of the connections, fill the keg with sanitizing solution, seal it and leave it for a few minutes, including a few minutes upside-down.
2) Connect CO2, and run the liquid line into a fermentor or something else that wants to be sanitized (so's not to waste the solution).
3) Turn on the CO2, and blow out the sanitizer until gas instead of liquid comes out of the liquid line. You can use low pressure if you want to go light on your CO2 usage and don't mind it taking a while.
4) Remove the liquid line and let the CO2 pressure build a little bit in the keg.
This leaves you with a sanitized, oxygen-free keg. When I have a batch ready to keg, I'll connect the outlet of the fermentor to the liquid in on the keg, and run a line from the keg's CO2 connection to the top of the fermentor. Then, let the CO2 pressure in the keg push the beer down the liquid line into the keg. This allows for an oxygen-free transfer.
Sorry if this is too far OT... I was actually reading this thread because I'm getting ready to build a new kegerator...
