    } elseif(is_single() && !is_attachment()) {
        $cat = get_the_category(); $cat = $cat[0];
        echo " / ";
        echo get_category_parents($cat, TRUE, ' ' . $delimiter . ' ');
        echo " / ";

You should use get_categories. It supports an exclude argument.

Change this

if (is_category()) {
    echo " / ";
    echo single_cat_title();
} elseif(is_single() && !is_attachment()) {

to this

if(is_single() && !is_attachment()) {
