You don't tell us how you ride, how much, on what kind of surfaces, etc. Important questions. That said, consider the following:
First, you are on the large size for a road bike. If you go for higher end racing equipment you may have problems if you put a lot of miles on her. Think hard before getting a carbon crank. You may well be better off on steel with widish tires.
Second, get yourself measured and look for the proper geometry of the diamonds to fit your dimensions as good as possible. eg if you have a long torso relative to your leg length you will want a bike with a longer top tube.
Third, you need to think about how you ride. The short wheelbases prevelant on many of today's bikes are responsive and fun to ride, but be careful going around corners fast, the back wheel can more easily come out from under you at high speeds. Longer wheel bases are better for longer rides, particularly if you ride alone and don't need to be manuvering in a group.
