Install Gmail Notifier from the marketplace and you will be able to get notifications for EVERY email, not just the first since the last time you opened the stock app. This notifier app just runs along with the stock app, it doesn't stay running in the background, but will produce new notifications everytime. Also, instead of the odd @ symbol google chose, this app places a nifty Gmail envelope icon in your task bar and I believe will place a "x" what ever number of emails which have come in since you last cleared the notifications. I don't know that one for certain yet, as I'm still playing with it, but the developer sounds like a cool guy who would add that in if enough suggest it.
Also, add to this the "Gmail unread count" widget, (also in the market) which replaces the stock shortcut, to produce a count bubble of how many unread gmails you have in your inbox....suh-weet! The widget is customizable in appearance too and you can select different colors, etc.
Remember, to prevent duplicate notifications, disable all notifications from the stock email app by hitting menu> (while the gmail app is open then) settings>disable notifications. oh, and the best part is, both of these apps are FREE!!
