settings and/or shortcode for facebook comments


I like to replicate what this site does:

(the facebook comment is at the bottom of the page’s body)

i.e., to use facebook comments only (no wordpress’:wink: — so,

1) do I need to uncheck all settings in WordPress/discussion settings menu?

2) I use photocrati, is there a special shortcode to have the facebook comments appear at the bottom of the page/post? I tried the “my_action_name”, but it didn’t show.
