I followed the suggestion for a spacer at the BB, and indeed this dialed out chainrub for two of the three cogs. (I think if I added another spacer, I would clear up the problem at the outermost cog, too; but that will wait till the next time I pull my cranks. Thanks for the good advice!
Interesting to note that I talked to the head wrench at my LBS, who said this is a known issue with Ultegra, and Shimano even has a recommended fix -- a set of spacers to widen the gap between the two chainrings themselves.
Either way, it's good to have an easy fix what what seems to be a common problem.
