Ditto the recommendation for the inline (cyclocross-style) brake levers, mounted on the flat part of the bars. They are an inexpensive solution (~$30-35) to helping with the reach problem, if you're not ready right now to trade in your bike.

My first road bike was much too big for me, but I was stuck with it for the charity ride that I signed up for because I had no time to deal with it. My LBS suggested the inline brakes, and they definitely saved the day for me.

Even though my new bike fits me very well, I'm actually going to get the inline brakes installed again. They're helpful on steep downhills, because I'm still not experienced enough riding in the drops, and my hands are on the small side even for Shimano short-reach levers.
