When you go to edit a capture page there is an option to turn it on/off for the page. There is also a section available to the admin called "Social API Settings" where it has your keys from the apps created for each service, as well as the ability to customize which group contacts are added to, and default title/message/url for the facebook blaster. If your prefer, we can paste any updates into the Social API Settings for you.
We have several tools that require apps to be setup in Facebook. Each app is slightly different. The easiest of them is the Facebook Add Contact tool. We recommend starting with this one if you will setup many of them as this will get you used to setting up Facebook apps.
