Two questions about my custom module

Hi, I've written a simple module to page tabular query results but I get different results depending on login. The main callback from the menu works great but some other functions don't fire for anonymous users. Do I need to register all these in the menu? Or use a different system?

Also, can any item be added to the Drupal 5 menu with drupal_goto as a callback? We'd like to add some dynamic menu items for admins. Is there a wildcard for paths?
