Comment with Facebook issues

Hello! I recently installed Ultimate Facebook. Set up the app, etc. I have an issue and a question with the commenting with facebook functionality. It's a WP 3.1.3 single-user site with the Invictus theme. Plugin is up to date as of right now.

I would like to use this plugin's functionality to use facebook for all commenting rather than the wordpress comments. I set up the plugin correctly, I think, but I am still seeing a wordpress comment box AND a facebook one on blog posts:

Also, is there any way to apply facebook commenting to pages as well as posts? Most of my site content is in the form of pages, and I would love to be able to allow facebook commenting on them.

Thanks for any help!
