How to create a menu item that returns Page Array data?

I would like to be able to use this module with thickbox so that I can display a node within a thickbox. Inputting node/21 (for example) does not work with thickbox because it tries to load the page theme as well and goes into a loop. I thought a good option would be to use pagearray.module in order to get a node's data and then display that in a thickbox of my own style. However, thickbox works by using what is in the href of the a.thickbox to get what you need into the thickbox. So in order to execute the pagearray_page function that pagearray.module provides, pagearray also would need a hook_menu implementation that could pass the $path variable as a callback_argument. I'm unsure of the best way to accomplish this, but I'm thinking it would be good to use something like /pagearray/node/21 in the anchor's href. (<a href='pagearray/node/21' class='thickbox' rel='gallery'>[link image]</a>)

Here is what I've put into the pagearray.module so far, but could use a little direction since this isn't working.

/**
 * implementation of hook_menu
 */
function pagearray_menu($may_cache) {
  if ($may_cache) {
    $items = array();    
    
    $items[] = array(
      'path' => 'pagearray/'. arg(1) .'/'. arg(2),
      'callback' => 'pagearray_page',
      'callback arguments' => arg(1) .'/'. arg(2),
      'access' => TRUE,
      'type' => MENU_CALLBACK,
     );

    return $items;
  }
}
