If you ever need to duplicate the functionality of the path of "/node/%node/edit", you can simply copy the following to and edit so it matches what you need.
In your menu hook, add this menu item:
$items['something/edit/%node'] = array(
'page callback' => 'something_edit_page',
'page arguments' => array(2),
'type' => MENU_CALLBACK,
'access callback' => 'node_access',
'access arguments' => array('update', 1),
); And then create the corresponding callback function to handle the request:
function something_edit_page($node) {
require_once(drupal_get_path('module', 'node') . '/node.pages.inc');
return node_page_edit($node);
} So when you visit "/something/edit/%node", it will display the same things as it would on the normal edit node page (except the "View" and "Edit" tabs).
