Like what was said previously, with your hybrid's geometry, if you change the handlebar, brake levers and shifters, you'll get a touring bike. Touring bikes can be good for road riding, just not as fast as a real road bike (weight, geometry).
Here are some things to consider (some were mentioned above):
-Road levers are not compatible with regular V-brakes, with the exception of the Dia-Compe 287 aero levers, which are not STI. If you use these, you can install Shimano bar end shifters. you may be able to use mini V brakes (with shorter arms) with regular road levers.
-Road stems and hybrid stems have a different size of clamp (road: 26.0 mm - hybrid: 25.4 mm). Like a previous poster said, you may be able to get a 25.4 mm road bar.
-Road shifters are not compatible with a mountain/hybrid front derailleur (from what I've read). You may need to change you front derailleur.
