Not sure I understand what you want here, but it sounds like you want to change the visibility/editability of fields based on role and display.

To change the visibility and/or editibility based on role, use something like this http://drupal.org/project/field_permissions

To change it based on display, use the "display fields" tab on the content type edit form.

I think this is what you are looking for
