Hey you can find those items from my armory since my name is on screenshot.
But I can tell those;
No headpiece used, i like my ponytail with bald head showing clearly like a real dwarf!
Shoulder: Gryphon Mail Pauldrons (That item is really rare world drop, green. Always check on AH)
Chest: Grievous Gladiator's Linked Armour (This chest piece doesn't show much but it gives you that tattoo like stripes on your arms. There should be also green version on same vendor)
Gloves: Tier from Dragon Soul.
Belt: I just used some random Wotlk belt but I guess better one can be find. Many are clipping with my beard so I just left it alone. You can pick any that matches with the set.
Kilt and Boots: Shaman specific transmog gear that you got from SoO shaman boss, as in chest.
Weapons: Heirloom one handed maces.
