I rooted using sdk platform tools/adb... It's really not that hard at all. Qbking77 has a videos on how to install Android sdk and how to unlock bootloader & root.. I used his root method and first round used same super user and didn't take so I used the su zip from ultimate Galaxy Nexus guide on xda: superuser-3.0.7-efghi and I put that zip on sdcard previous to rooting and after I pushed cwm to Gnex I flashed that su zip in recovery and all was good.
Note: I cant believe people are actually flashing roms when they aren't yet made for our phones!? I'm going to wait on that.
