In-depth questions about Cybertron Balancing Act

I know they were released through the collector's club, but what were they in terms of storyline continuity? Can someone giv eme an overall synopsis of where this fits into the Transformers mythos?
I know there was some sort of multiversal aspect to them, as it showed the old marvel Universe when Optimus' head was removed. Can anyone explain what/when the other scenes were from?
it says the stories were continued in teh collector's club... were they text-based, or more comics that are exclusive to the Club magazine?
Any other general info? I like dit, but I was lost
