It works! I’m back on my MacBook Pro.
Having been forced to backup and clear my laptop drive to prepare for repair, I wasn’t confident the process I was using would easily restore everything. Fortunately, I was able to completely restore my laptop with no hiccup. The whole process took about five hours: one hour to prepare my backup image (ie. Scan Image for Restore), two hours for restore, and two hours to verify. This was all done via Target Mode over Firewire 400 from my PowerMac G5.
