Which Mac notebook is best for me?

This will be my first Mac; coming from the world of Microsoft. Although I do know how to work a Mac, I'm not sure which Macbook (or Macbook Pro) to purchase. Requirements are: music, photo, office, internet, video, and graphics (pro would be best). Now, I don't really speak computer-lingo yet, I simply know I want it to be a very fast Macbook that can also store a great deal of data. So any recommendations, I'd really appreciate it. Thanks guys.
