Test ride them all and see which one you like.
I know the Vaya is getting some buzz on the Commuting forum. The Bosanova looks interesting and Jamis usually gives you a lot of bike for not a lot of money. However if you are planning to go touring longer chain stays help with heel clearance.
Judging by the bikes you are looking along the lines of light duty touring bikes (as compared to cyclocross with tend to be a lot more sportier). Check out the Jamis Aurora and Bianchi Volpe. Also, the Surly Cross Check (even though a cyclocross) might fit the bill as it doesn't seem to be race oriented.
