The "Edit" only shows if you are logged into the site with enough permissions to edit the page content, so your site visitors shouldn't see it.
For the "Comments Off", try following the instructions found Here
and see if that helps.
If not, feel free to PM me login/FTP information for your site so I can make the changes for you (NOTE: the login can be a new account, but it must have admin access for me to edit theme files).WARNING!: Do Not post site login details on an open board, always send through PM.
