{wp-core}{Thme:Twenty Twelve } Remove Admin Submenu items

Hello , I am just finishing off a site for a client and I was editing the role capabilites and cleaning up the menu. I have a made a child theme for twenty twelve and manage to remove all the menus and submenus i needed from the editor role. But been having problems to remove the:

• Apearence>Theme options,
• Apperance>Header
• and Appearence >Background

.

Initialy i used the :

// Edit Editor User Roles
function add_theme_caps() {

  $role = get_role( 'editor' ); // ou subscriber, nao sei que role tem o cliente
  $role->add_cap('edit_theme_options' );
  $role->add_cap('moderate_comments' );
}

then after couldnt really get to the submenu items that way so i used the following method .

function my_remove_menu_pages() {
	if(!current_user_can('add_users')) {
		remove_menu_page('options-general.php'); // Settings
		remove_menu_page('link-manager.php'); // Links
		remove_menu_page('tools.php'); // Tools
		remove_menu_page('edit-comments.php'); //comments
		remove_submenu_page( 'edit.php', 'edit-tags.php?taxonomy=post_tag' ); // Post tags

		remove_submenu_page ('themes.php', 'themes.php');
		remove_submenu_page( 'themes.php', 'themes.php?page=options-framework');
		remove_submenu_page( 'themes.php', 'themes.php?page=options_framework' );
		remove_submenu_page( 'themes.php', 'themes.php?' );
		remove_submenu_page( 'themes.php', 'themes.php?page=costum_background' ); 

		//unset($submenu['themes.php'][5]); // Removes 'Themes'.

	}
}
add_action( 'admin_init', 'my_remove_menu_pages' );

All seems to work fine except the the remove os those last three items.
In the bottom i have commented another way to do the same thing but not really sure who is who with the number system.

Can any one helpme with this ?
