Well, I think I both figured out how to fix it and how to break my NC all at once. No applause, please.
I could see no way to interrupt the Bootloop, other than insert a bootable SD card. Problem is, that still wasn't going to allow me to change the system, since I'd be running from an SD card.
There may have been other ways to fix it more easily, but I opted to simply restore my phone to factory with the Bootable CWM SDcard. That went fine. Problem is, once I had everything wiped and re-installed, I had to reboot my NC. When I did, I still had the SDcard in the slot. So, of course it booted right back into CWM. So, I decided to try removing the SDcard as soon as the screen went blank and right before it restarted. Brilliant, I know. I definitely didn't think that one out.
Anyway, now my NC won't do a thing. NOTHING. I'm holding on to a prayer that the battery simply gave out after all my toying around (I had in fact thought a dead battery might be my only way to exit the loop). But, my guess is that's not the case. Call me a pessimist.
At this point, I'm thinking that I'll be returning my NC to the store tomorrow. Sweet.
