Also, making a nandroid backup is using the recovery and backing up right?
Do you mean go back to stock using Odin? No, you don't have to wipe. Odin will replace everything. However, I do like to wipe everything using recovery before I go back to stock. I even do that before restoring a backup. If you want to save the ROM you're on now, yes back that up first and yes a nandroid is a backup made in recovery. If you want to save room and not backup the cyanogenmod ROM you're on now, you could always flash it again later.
Look in settings > accounts and make sure your contacts are synced with Google. After you use Odin and go back to stock they will restore themselves. If you are just restoring your rooted stock backup in recovery, everything you had will still be there.
