If I do a factory reset will it roll my EVO back to 2.1?

No, it only erases downloaded apps and settings. It doesn't downgrade the software. You will have to re-download any apps that you want to re-install. Don't worry about any apps that you paid for because they are linked to your Google account and you won't have to pay again.
