Bunch of questions: Maestro D' and her two gangs.

With right improvements the Maestro D' is able to have two gangs. (The real gang (3-harm gang small 1-armor) and cast & crew who are packing  (2-harm gang small 0-armor)). I'm not going to delve into Leadership or Pack alpha territory, as it has been discussed here: http://apocalypse-world.com/forums/index.php?topic=297.0

How would you play this situation?
Are the gangs clear separate entities? Do they overlap? Am I misinterpreting the rules?
Is 'the bouncer who knows his biz' also a clear separate entity or a part of either of gangs?
Can Maestro D' use other PCs as parts of her gang if they are part of her cast & crew and she's chosen that they're packing?

Spoke about these questions with a friend earlier and unbeknownst to each other he also asked a similar question here: http://rpg.stackexchange.com/questions/83235/what-happens-if-a-character-has-more-than-one-gang

Feel free to answer to either of threads. I'm monitoring both.
