So my clerics are in the Shroud now...yay!

I already know what I want to make for my healing focused cleric, but I need some help fine tuning the items for my battlecleric.

I'm fairly certain one weapon is supposed to be holy, acid burst/blast, transmuting/keen/etc. My question is, should the other have a +2 exceptional stat on it? AC seems wasted, as I'll never have enough to matter.
