BB Device Software :: Prevent Email Messages - Appearing In Messages?

I want to be able to check my email thru the GMail application; get notifications for my Yahoo Messenger, missed calls, voicemails, and SMS Text and MMS messages thru the BlackBerry Messages app; and my Gmail calendar thru the BlackBerry Calendar app.

I can't figure out how to make my email NOT appear in Messages. So, I created a dummy email account that gets no email and set that up as the default email account. Now I get my real email thru the Gmail app, and all the other notifications thru Messages (and no emails in there). Great, but the Calendar app won't work with my Gmail account because it only wants to connect to the dummy gmail account and to Facebook. I don't want Facebook to touch my calendar, and I have set it as such in the Facebook App options, but it still does. Using Google Sync, I managed to get my real calendar to show up in the Calendar as Default. When I run the sync, the appointments I created in the online Gmail calendar appear in the Calendar as being on the Facebook calendar.

From the Calendar, I can not create appointments for my real Gmail account, only for my dummy account and for Facebook. If I delete the appointments from the Facebook calendar, then after syncing it deletes the appointments from my online Gmail calendar. I think what I need to know boils down to "how can I prevent email from appearing in Messages?". If I can figure that out, then I can delete the dummy account and set up the email as my real account and then the calendar should work correctly.
