I did the entire root process straight from my phone! I originally tried to download the update.zip file with the default browser. It said "this content type is not supported"! WTF? Who makes a browser that can't download zip files? I used Skyfire to download the zip file, then renamed it and put it in the root with file manager. Performed the steps and worked like a champ! I'm running Titanium backup now to get a good backup before I get rid of these AT&Greed apps!
