Hay Sancta, have you seen the FATE module for Exalted that's been floating around.  I think maybe it was the WW forumite Mouse that made it?  It has a pretty simplified list of skills, based on Exalted.  They also use Mental conflict as trying to change someone's mind and Social conflict being about changing someone's reputation.
As far as I can tell, these are the list of Skills used in Mental or Social combat:  Empathy, Integrity*, Presence, Contacting, Bureaucracy+, Resources+, Socialize*.
*Determines Stress track.
+Kinda edge cases, could be taken off the list.
Now that I look at it more closely, I can't actually find a mental attack trapping in there.  Huh, well it's interesting to see someone else's thought process anyway.  There seems to be complete overlap between Mental and Social skills.
