Did you ever get this to work? I'm trying to do the same thing, remove the category dialog title AND embedded products, basically just have the category description showing and thats it:
Code:
{* $Id: dialog.tpl,v 1.25 2005/12/20 08:50:49 max Exp $ *}
{if $printable ne ''}
{include file="dialog_printable.tpl"}
{else}
{if $cat ne "2"}
{else}
{/if}
<div class="DialogTitle"><img src="{$ImagesDir}/down2.gif" alt="" style="float:left;" /> {$title}</div>
<div class="DialogBorder">
<div class="DialogBox">{$content}</div>
</div>
{/if}
