I finally resolved my ticking issue today. For me it was the bottom bracket, but it wasn't that it was broken, it was that it needed to be re-greased. I greased the pedals (the bearings - I wanted to do the threads also but I couldn't get them off the bike!) and when that didn't work I took it in to my LBS. We tried re-greasing the pedal spindles and tightening the chainrings, but when that didn't work my shop guy turned to the BB. I just picked it up and rode it home and was amazed at how silent it was. I'd forgotten... it was SO nice.
