For a pre-heroic chest I don't think you can beat
[Sly Fox Jerkin] and it is easily obtainable off of vendors. You get ridiculous amounts of reputation just running Hyjal so should be no dungeon running required.
As for boot enchant, it is the best if you don't care about run speed. If you want a run speed one, it looks like the old Tuskarr's 15 stamina one is probably still the best eding out the 25 agility one. The 35 mastery one seems really bad.
I've got a question about the OP's gear list. On the Elementium Poleaxe and Elementium Destroyer's rings he reforges mastery to dodge, instead of crit. Now I can see on the rings why this is done, the mastery stat on the ring is higher than the crit stat, so the reforged dodge is a higher value than if the crit were reforged. But on the poleaxe, the values are equal. Why is the mastery reforged to dodge instead of the crit, when both stats are equal and both the pre-heroic and pre-raid AEP list shows Mastery as higher rating than crit?
Edit: Just had it pointed out to me I missed that there was a new stamina on boots enchant, Earthen Vitality, which blows the agi and mastery ones away.
