Since you have 10.3.8 on the external drive you have a few relatively easy options. 1. If possible boot from the 10.3.8 drive and run the updater again choosing that drive as the one to install to 2. Use a program such as Carbon Copy Cloner to clone the drive you have already updated to the external firewire drive.
