Social media integration, including set up of Facebook Open Graph \"Story\"

On our Joomla site: A. For Facebook, we would like to use JFBConnect (already installed for log-in) to automatically share a "Story" via "Facebook Open Graph" on the User's Facebook Account for the following actions: 1. Users signing-up for an account on our website, 2. Users uploading a new Project Photo Album or Photo to our website, 2. Professionals-Contractors placing a bid on an open Project auction in our website, and 4. Users "liking" a Project Album or Photo in our our website Gallery. B. For LinkedIn, we would like to use the LinkedIn API (or JLinked...whichever is easier) to automatically share a link on the User's LinkedIn account to "new Project Auctions" posted on our website by the User. C. For Pinterest, we would like to add a "Pin It" button to our Gallery that allows Users to "Pin" pictures from our website Gallery to the User's Pinterest account. (Similar to "Pinteresting" extension description, but we are already using the "hovering over picture" text function for another feature, so we need an actual button)
