Add facebook, Twitter comments to cute news

Hi all. I read whole forum but can't find good working script for facebook, twitter comments(i want both on my page).  Now I use facebook tool and it works but have the same comments. Can someone help me?

and second problem: I want to integrate my site to facebook/twitter(post news etc). When i post link to my page or to specific comment Facebook show only whole page discription and image thumb. If there is any way to post link on facebook and FB show last news(with thumb photo from that news or when i put link to specific news) I've found one script here cutephp but i'm too stupid(i use cutephp for hmm few days) to get this work.

Thank you
