Is your email server like gmail/hotmail, or is it from your ISP (like msn.com?).
If you have a data plan, you should have an internet email setup in your phone. Click that and it will take you through the steps. You will need your username and password.
The first thing you need to do is call your Cell Phone provider and ask about a plan that allows you to send\recieve data with your phone. For email\web you will need a data plan.
