How do you get the current-menu-item ID?

1. A little late perhaps, but there is one more way of doing it:

   $menu = wp_get_nav_menu_items($menu_id,array(
      'posts_per_page' => -1,
      'meta_key' => '_menu_item_object_id',
      'meta_value' => $post->ID // the currently displayed post
   ));
   
   var_dump($menu[0]->ID);
   

   Since menu items are post-types you are able to use all the WP-Query params, even a meta query. The code above selects all menu_items which are connected to the current post, from the menu you specify via $menu_id.

2. This should solve it How to get current-menu-item title as variable?

   but change

   $GLOBALS['wpse16243_title'] = $menu_item->title;
   

   to

   $GLOBALS['wpse16243_title'] = $menu_item->ID;
   

   and now you can use the global variable $wpse16243_title to get the ID

3. The best way would be to use the nav_menu_css_class filter. Something like this would work:

   function wpse19375_nav_class( $classes, $item ){
     if( !in_array( 'current-menu-item', $classes ) )
       return $classes;
     // $item is a 'current-menu-item' object.
     return $classes;
   }
   
   add_filter( 'nav_menu_css_class', 'wpse19375_nav_class', 10, 2 );
