Ok I think I know what you're looking for

I've attached a picture of what it will look like (although your's will be a bit different, mine has a border around it from the output profile I have selected, the text bits should be similar.)
So start with a new copy of template.xhtml and replace this:
Code:
<tr class="cbj_rating">
<td class="cbj_label">{rating_label}:</td>
<td class="cbj_content">{rating}</td>
</tr>
<tr class="cbj_tags">
<td class="cbj_label">{tags_label}:</td>
<td class="cbj_content">{tags}</td>
</tr>
</table>
<div class="cbj_footer">{footer}</div>
</div>
<hr class="cbj_kindle_banner_hr" />
<!--
In addition you can add code to show the values of custom columns here.
The value is available as _column_name and the title as
_column_name_label. For example, if you have a custom column with
label #genre, you can add it to this template with _genre_label and
_genre. Note that the # is replaced by an underscore. For example
<div><b>{_genre_label}:</b> {_genre}</div>
-->
<div class="cbj_comments">{comments}</div>
</body>
</html>
with this:
Code:
<tr class="cbj_comments">
<td colspan="2">{comments}</td>
</tr>
</table>
<div class="cbj_footer">{footer}</div>
</div>
<hr class="cbj_kindle_banner_hr" />

Hope this helps!
