From memory that theme doesn't have the option to hide compare at prices so you'd need to add some code to hide it.
There'll be a bunch of versions of that theme floating around so would be useful to get a link to your store. Seeing the theme live makes it easier to suggest any css (style) edits that you may need to make.
