Great work,
Please add these as well:

  $items['admin/people'] = array(
    'title' => 'People', 
    'description' => 'Manage user accounts, roles, and permissions.', 
    'page callback' => 'user_admin', 
    'page arguments' => array('list'), 
    'access arguments' => array('User Settings'),
    'file' => 'user.admin.inc',
    'file path' => drupal_get_path('module', 'user'),
    'weight' => -4, 
  );
  
  $items['admin/people/create'] = array(
    'title' => 'Add user', 
    'page arguments' => array('create'), 
    'access arguments' => array('User Settings'),
  );
  
  $items['admin/people/people'] = array(
    'title' => 'List', 
    'description' => 'Find and manage people interacting with your site.', 
    'access arguments' => array('User Settings'), 
    'weight' => -10, 
    'file' => 'user.admin.inc',
    'file path' => drupal_get_path('module', 'user'),
  );
