The Sprite people provide good support, you should contact them to get your registration sorted out. The HTC backup is just a special build of the Sprite software but I think it may be timebombed. I'm not sure of that though.

Overall you are asking a really loaded question. You can backup most everything with Sprite backup. I can't recall if it restores email settings or not, but it probably does would be my guess. The question you didn't ask is SHOULD I restore a backup after I flash the rom. Generally this is a dubious undertaking. It may work OK(ish). But you're probably going to be "restoring" things over your new ROM, and if the kitchen used different versions of a given program, your settings may get royally screwed up.

So, conceptually Sprite Backup is probably about the best sw out there to do this with. But you might be very unhappy with the results. The least of which won't be when you overlay new ROM code with the stuff from your old backup.
