Trouble adding comments plus

Hi,

I have been through the various questions and tried a number of ways to implement comments plus but I can't get it to work without breaking my theme. When comments + is showing my right sidebar is pushed down the page below the comments sections.

Also, the commenting tabs are not shown in the comment area (facebook, Twitter, google etc) and the options to follow via email etc are duplicated.

My site is http://www.gizchina.com. I have removed comments plus for now but hope you can help me intergrate it at some point thanks.
