I'm aware of the process for restoring mailboxes from backup, however I've never dealt with restoring from scratch.
Backup everything in the \Program Files\Exchsrvr\mdbdata to another drive (or tape, or whatever.....)
Rebuild your server and then install exchange. When you install exchange, throw the /disasterrecovery switch.
You will be prompted for the mail store (which is in \Program Files\Exchsrvr\mdbdata) and it will automatically pull over all of the AD settings, if you have another DC in the forrest.
A suggestion, don't make your EX server a DC as well.
