So.... I was running OTA stock. Not rooted, with a locked bootloader.
I downloaded Wug's Galaxy Nexus Root Toolkit:
Wug's Galaxy Nexus Root Toolkit
Unlocked my bootloader, which wiped the phone.
After that, I had to set up the phone again (with stock 4.0.4) and then in the utility I went to Advanced adn then I flashed the ROM from my PC. It copied the zip file to my phone, and then booted into a temporary CWM. From there I followed the onscreen instructions (well, I followed the instructions on the SECOND time through) and did a factory reset, wiped cache, wiped the davlik cache and then installed the ROM. Booted right up.
I tried to restore my stuff from the backup I made, but it wouldn't work using the toolkit, so I did it manually (just copied over the pictures, movies, and music I had on my phone).
I've got about 0.04% of the knowledge that these XDA folks have, but I was able to get it working without bricking my phone, so that's a testimate to how good that toolkit is and how well the ROM works.
Hope this helps!
