Hiya Keith,
Yeah, I misunderstood your issue, but you've explained it great this time. First off, the comment/like buttons will show all the time, regardless of whether the user is logged into Facebook. If they want to put their input in (like something or make a comment), they'll need to log in. However, if they aren't logged in, they can read previous comment and see the Like button. Hope that makes sense and seems like the right functionality.
As for multiple comment boxes using the same ID, you're correct that it should be different per article. If you're using the JFBCContent plugin, that should be taking care of putting a unique comment box on each article. If you're manually inserting the { JFBCComment... } tags into each article, you'll need to make sure that you specify a unique xid parameter for each one. You can read more about the comment tag below:

For the content plugin, we create an id like xid=content_23 (content = com_content, the built in Joomla article manager, and 23 is the ID of the specific article). Looking at your home page, I currently only see 1 comment box with a xid=1. I'm not sure how you've configured that, but if you set the comments to display on all articles, look at the HTML and find the xid=?? code. If it's the same for all articles, that's why the comments are the same.
Hope that all makes sense, help you narrow down the problem, and helps. If you have other questions, just let us know!
Thanks,
Alex
