titansteel bonecrusher (I think, it's a 1h dps mace) is a good one to get for enhance. It'll be your main hand for awhile. it's crafted, and probably won't run too much gold. honored ebon blade will get you their fist weapon, which is offhand only, or you can grind sons of hodir until you can get their axes, which are just as good (better for orc shamans due to +5 expertise, and they're one hand so you can dual wield them).
I'm not sure what LW crafted epic dps mail there is. I'm sure some exists, but I can't remember the name of it. in terms of overall stats, you definitely want agi and I would say enough hit rating to have 9% hit, maybe slightly more so the spell hit cap is close to reached. I can't imagine actually stacking enough hit for the spell hit cap, but I'm kind of confused on if dual wield spec only applies to melee or if it also applies to spells, since it just says it increases chance to hit by 6%. beyond that, all you take is regular hunter loot, and any mail with expertise on it.
