It's a very long story too long for an  email actually.
you should follow the abinit tutorial instead
   http://www.abinit.org/ABINIT/Infos/Tutorial/welcome.html
the lesson 1 on response function shows examples of abinit+anaddbb usage.

as for the character tables you can find them  in this web-site:

   regards pietro
