Changing ROM basic question, help needed

[dahray02]

OK, so this has been my first WM phone and i've learned alot since last nov when i got it. I've customized the hell out of it and got it where i want. I'm using an older JD ROM, but i keep seeing that Mighty ROM has better battery etc.. so my question is, is there a way to switch ROMs and keep all my programs and settings the same, I really reallllyyy dont want to have to redo everything that I have done over the last 5 months. I have Sprite Backup, but I'm sure i cant do a restore from a backup and a different ROM...and i'm sure how to use the Upgrade feature, all that level 1 stuff..etc....any help please, thanks
