It didn't take long before I had clicked my way over to Sheldon's site and discovered that I may be experiencing spoke rub. Armed with this new knowledge I went out into the garage, and after a few minutes of troubleshooting I had identified exactly what was causing my problem. Not having the tools and know-how to fix it, I had to take the bike back to the LBS, but since I could tell them exactly what my problem was, they fixed it right away.
So yeah, for me this thread was great. And considering the wealth of information in the OP I bet the same is true for many others.
