Custom code for posts

Hi. I have the Catch Responsive Pro theme and was hoping you could provide custom code to remove the date, posted by name and the "Leave a comment" text, icons and links for all three for posts. I turned off comments from all pages and posts and yet there's still a link at the top of the post that says "Leave a comment." I want to remove that link and text as well as all the other links, icons and text for posts (date, posted by and comment). I couldn't find where to turn this off so I assume custom code is required to do that. Thank you!!!
