List custom taxonomy as navigation – taxonomy pages with all it’s posts?

You can create the file taxonomy-event_type.php. That will be used when you use the url /?event_type=lectures or /event_type/lectures.

You can use wp_list_categories by adding ‘taxonomy’ => ‘event_type’ to the arguments (see http://codex.wordpress.org/Template_Tags/wp_list_categories#Display_Terms_in_a_custom_taxonomy)
