Changes to a Wordpress 3.0.1 website(repost)

I need some changes to a word press website. On the front page, it shows the last comment - I also need a reply button with an ajax box that opens and closes whiteout reloading the page - something similar with the way comments work on this page <[login to view URL]> I have a nice way to show a twitter button and a rss feed button I would like a facbook button there too Add facebook like button somewhere on the post title bar on the fronpage and in a similar way inside the post. Other small changes could be required too. ## Deliverables I need this done in the next few hours. I need a coder who speaks "wordpress" native.
