I'm afraid I went way back in time on the english.php file and it IS NOT where you would need to go to change this.
The file that may be doing both things badly is the tpl_header.php file. It should be in the common directory of your custom template. Line #70 establishes the logoWrapper. Line #71 puts the link and the logo onto the page.
<div id="logo"><?php echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">' . zen_image($template->get_template_dir(HEADER_LOGO_IMAGE, DIR_WS_TEMPLATE, $current_page_base,'images'). '/' . HEADER_LOGO_IMAGE, HEADER_ALT_TEXT) . '</a>'; ?></div>
You might be able to do away with the logo altogether since you are not using anything in it. That would be done in the stylesheet where it says #logo around line #79. Change it to
#logo {display: none}
However, you still have the logoWrapper showing up twice in the page source. You will need to find where that is happening.
