BB Software :: Unable To Open Email In 3520?

I am very new to Blackberry, like just 2 weeks, I am loving the phone, and im getting quite used to it, but some things puzzle me like my email, I have a Blackberry Curve 3520, I am with T Mobile and my Email is with Gmail, the problem I am having is I get a email from me if I send it through my blackberry, e.g. Hello as a test message, But none of the emails like "welcome to blackberry support forums etc, that are in my outlook, also, I am not getting the little red star telling me there is a new message, I do get that star when Blackberry sends me a mail saying "Your hand held has been registered with the wireless network" but that is it, Is there a setting I need to sort out in Outlook or my Blackberry
