After that, I decided to set up my home account (my wife and I use it for our home accounts like telephone, electricity, etc.) and I added that by opening Gmail (using the shortcut to Gmail) pressing Menu, Accounts, Add Account. I added the log in info for the second account and now, at the top of the app where there's a black bar displaying what folder I'm in (currently Inbox), there's a new button of sorts that shows my primary e-mail account which when pushed allows me to switch to the other account.
So I have one Gmail shortcut that works for both accounts, gets e-mail notifications for both, and sends using the account I want when I select it at the top. No separate shortcut and both are independent of each other. I don't even use the e-mail application.
That's how it works for me.
