Get Facebook loginbutton to appear when users press login

Hey

We are in the proces of building a new blogging network but have some trouble getting the Facebook plugin to work.

We can not get the Facebook login function to work on the page.

I want it to appear when the users press the loginbutton on the frontpage. See the link:

I also have trouble with merging the comments.
We have GP Sitewide Comments already but after installing the ultimate Facebook plugin it somehow interfere with the comment section(to the right). See the link:

Best regards
