hi! im using the same armour set. i found that the shattered sun offence rep shield(yellow one) looks quite good with the armour set. im also using the Brutalizer(sp?) from hyjal(?) [its still early for me here lol]since i have the axe from the first boss in DS. if we had a tanking mace option, id be using the gold mace from prince(last boss in Kara) as i think its looks the best for a weapon with that gear. hopefully one day blizz will lift the restrictions slightly on transmogging to allow any 1h -> 1h conversion. hope that helps.
*edit: should have added ive had quite a few tells and positive comments about my transmog set XD
