Well, here's a copy/paste of Serf_John_RS.  (You don't need to wear peasant garb, of course.)  I use a masterwork war spear with three of whichever throwing weapon my mood dictates at the moment (usually throwing lances, since they're so incredibly satisfying).  If you wanted to divert more focus to throwing, I'd switch three or six agility over to strength.  
Then again, 36 strength, 3 agility will work too.  You can't really go wrong with throwing if your strength exceeds your agility.
