List of template suggestion used for a node
I'd go and get the Theme developer module.  Simply get the element you want to theme and click on it - then you'll get a list of any template files and/or theme functions that were called in the processing of the element you clicked.


  Firebug for Drupal themeing. See the screenshot and screencast. Note
  that this module injects markers into the DOM to do its magic. This
  may cause some themes to behave erratically and less capable browsers
  may make it worse (especially IE)/. Enable it when needed, and disable
  it afterwards.
