There are several good touring wheel combinations as were mentioned in the previous posts.

The wheel I like for 130 mm dropouts, and have the most touring miles on is: Velocity Dyad 36 hole rim, Ultegra (my wife got the Ultegra's) or 105 hubs, and Wheelsmith double butted spokes. They are a good compromise between weight and durability. My wife and I have put a lot of loaded miles on those wheels without a problem. I also have the same rims and spokes built on XT hubs. I've also had pretty good experiences with Tiagra hubs on my CX bike. The hubs held up well, but the stock front rim and spokes caused me some problems. However, it was abused and had a lot of miles on it. I replaced the wheelset with the 105 wheels mentioned above.

Look at Universal Cycles "Custom Wheel Builder" site, and if you have any questions give them a call. They are great to deal with and build an excellent wheel. You can play with the site and spec your own build. Universal Cycles -- Custom Wheelset Builder

One thing you may want to check is how wide of a rim your brakes can handle. I have a road bike similar to yours, TREK 1000, and I'm not sure a wide rim would work well on it. I know I can't get a 28 mm tire by the brakes without deflating the tire. The Dyad rim is a little narrower than some of the other touring rims.
