Will the TP be the right phone for me? email questions!

[tweaked21]

I ordered a TP last week and it will be here tomorrow (Verizon). I'm worried about whether or not it will be the right phone for me. I currently have a Nextel Blackberry Curve 8350i. I love how the Blackberries handle email, but I love all the rest of the functions that other PPC phones have. One thing that made me pick the TP is the fact that it has a touch screen AND a full Qwerty keyboard. I'm just not sure if it will perform to my expectations with email. I don't want to have to go download my email messages periodically. I'm wanting it to notify me when I have new mail. I have 3 Gmail accounts, and an email account from my own domain that I want to setup on the phone. Will I have to go out and download the messages (check my email), or will it notify me when I have a new message in my inbox?

If it does not do what I want, I will probably return it for a Blackberry storm, though I don't like the fact that it doesn't have an actual keyboard.
