Is a 38 the smallest inner ring you can run on an Ultegra double crankset? If not what are the options?

I believe that 38's are smallest chain ring you can get. Unless, you switch to a Ultegra triple, in that case, you get 52-42-30.
Kind of tempted to go that route myself. But I wonder what would happen if ....

there are 'compact cranksets' available now and more in the near future. They offer smaller chainrings on a 110 BCD pattern instead of 130 BCD like Ultegra, etc.

I've provided a link to a pricey FSA version and a reasonably priced Stronglight version. the FSA will fit your Shimano Octalink BB, the Stronglight will not and will require a new square taper BB.

I understand Ritchey will be introducing their compact version soon. It will be Octalink compatable. Price TBD.

Hope that helps. Cheers.
38t is the smallest for a 130 BCD. (nm)TFerguson
