I'm not sure I understand your question. Once you have fully rooted your phone, which means unlocking nand and flashing a recovery image, you can then create a complete backup image of your phone via Nandroid backup.
Obtain root access
Flash a recovery image
Make a nandroid backup
Flash a ROM
You want to do it in that order. Is that what you mean?
