I've read your other thread.
I would suggest stop worrying about the busses. You are thinking analog.
I don't think it was mentioned that first you should solo what you are trying to bounce.
Then do: select the time frame, then 'bounce to track', select the preset 'what you hear', uncheck all the the unnecessary boxes and hit ok. done.
I don't know why Jeff suggests 'export'. Well, I mean, unless you want to export.
