Oghash is using Chainmail +2 currently (not a Chain Shirt +2), so the armor isn't an upgrade. She wouldn't use the magical mace unless dealing with DR that wasn't being overcome by gratuitous damage... I think the gold should continue to be used to further pay for the corruption and fall of the town. We will be murdering and looting any remaining stores from which we would otherwise buy things, I think.
Long story short, Oghash isn't interested in the loot right now.
