The slow (Sha's Legacy) and Growl of the Panther for sure. Also the Emphatic Fury disc.
Since you're going to be there for a while add the pet, the pet proc, the pet haste, the nukes, the Rake disc, Spiritual Ascendance, Bestial Empathy.
And if you solo a lot, add Focus, SV, regen, and the general purpose heal.
But unless you go to a tradeskiller for them, you're going to get most of what's left anyway...nature of rune turnins.
