You do have to have a Google account, but you do not have to use the Gmail email client application. Your Google account is required to make Market downloads.
Personally, I use the built-in HTC mail app for my Google account (gmail.com) via ActiveSync. You could also configure it using POP or IMAP. IMAP is preferable to POP. I prefer ActiveSync.

how does the email app on the tb work?
- does it have the ability to get email as soon as they come in?
- or does it have to be setup up on a sync schedule?
The Gmail app is push email, if you rely on gmail then it is a good option. If, like me, it is secondary then you can relegate it to imap or pop in the regular (or for me maildroid) app without concern. I needed better email for my other accounts more than i needed better gmail
