Sounds like the front derailler needs to be positioned better. I've had a similar problem using the smallest cog when in the middle ring of a triple crank. Fixed it by moving the front derailler a little closer to the chain, but not so close that it made any noise.
The crank being 9 speed should have absolutely nothing to do with it. The only downside to using a 9 speed crank with a 10 speed chain would be slightly slower shifting. The only downside to using Tiagra in place of Dura Ace is some weight. How much do you care about a few ounces?
According to weightweenies, Tiagra standard crank is 975 grams with BB and Ultegra SL Compact FC-6650-G is 811 grams with BB. 5.7 ounce difference.
