So you set up
a new resources folder with the jacket folder containing template.xhtml and stylesheet.css?
If you've done that then you can edit the template.xhtml in notepad or similar text editor. If you remove the highlighted code from the template.xhtml it will remove the Tags, Ratings and the extra lines around them and your new metadata jacket would look like the second image. You will have to re-polish your books to get the new jacket in there.
Hope this is what you were looking for.
