I'm not entirely sure whether this will be of any use to anyone but this adjustment makes the slideshow appear only on the home page and fixes the true/false status
Code:
<!-- begin edit for ZX Slideshow -->
    <?php if (ZX_SLIDESHOW_STATUS == 'true' && $this_is_home_page) {
    require($template->get_template_dir('zx_slideshow.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/zx_slideshow.php'); 
     } ?>
    <!-- end edit for ZX Slideshow -->
