I would go with the 26 tooth inner ring if I was you - it will make front shifting a little smoother and reduce the chance of dropping the chain (although still use a chain retention device like Third Eye or N-Gear), and your lowest gear will be plenty low enough. Are you aware of how widely-spaced the gears are on the 11-34 cassette? I would want something with tighter spacing for road riding. Even 11-32 is a bit better.

My Trek 520 now has 26-42 chainrings up front and a BBB 12-28 10-speed cassette out back, which I find to be ideal for touring - lots of closely-spaced gears, a good range for touring, and minimal shifting with the front derailleur.
