Facebooker is no longer supported I recommend using Koala gem: https://github.com/arsduo/koala/wiki

There is a very comprehensive article here: http://www.packtpub.com/article/facebook-application-development-ruby-on-rails

And several existing plugins for this purpose like 'rfacebook', 'facebooker' or 'facebook-rails'. 'Facebooker' definitely has Facebook Connect abilities.
