Depends on your budget. If you're just doing group rides, charity rides, and like to do long distances you should try to get a relaxed geometry bike. An example would be the Specialized Roubaix. It's got a more laid back geometry/longer wheelbase making the bike comfortable for longer rides, while still being as fast as most road bikes.

Touring bikes and road bikes are very different. Touring bikes use cati-lever brakes to allow for bigger tires. They also come with eyelet holes and braze ons to accommodate racks and fenders. Also the geometry a different, it's more relaxed with a longer wheel base. Touring bars are also less aggressive then road bike bars. They also have much different gearing. Road bikes are aimed to be fast, while touring bikes are aimed at having really low gears.

If you want to get a mix of the two, you may want to consider a cylcocross bike. You can still be "road bike fast" on a cyclocross bike. Some cross bikes have the necessary holes to hold racks and fenders.
