I think I figured something out. I did install ROM Manager, but somehow I had also installed ClockworkMod. So, when I rebooted into recovery I was actually booting into ClockworkMod thus "doing it right" but going about it all wrong.
So I have since managed to flash my SGP 5.0 back to FacSpec so I am ready to try again... now that I am a little smarter... I hope.
