I was sleeping. Then saw Steve was answering your questions.
I don't know what you mean by adding BIS to Outlook. Desktop Manager does not sync email. You cannot read your @carrier.blackberry.net email in Outlook.
Did you just add the gmail address in BIs, nothing else? You didn't sync your blackberry with your google account address book and calendar? If you don't want the google address book, you'll need to clear all address book databases as Steve advised, and then undo whatever it is you did with google.
I don't understand what you are trying to do with the primary and seconday comcast email stuff. Why are you forwarding email? If you add your comcast address to BIS, it grabs a copy of the email and pushes it to the handset. Set Outlook to leave messages on the Comcast server.
