Dropping defence is an easy option running around 550 isn't difficult and covers options, nearer 540 if you can add in some dps gear (dps weapon, rings or neck are easy alternatives.)
Shield enchants are pretty weak atm, really a choice between def (if needed and you don't) or stam vs plating which is where dual shields come in.
Two stats you've missed entirely are pretty key in balancing gear sets, being hit & expertise. Are the above options including being hit/expertise capped? Given taunt being borked not being hitcapped in the current climate is a slight disadvantage, covered elsewhere and all that.
Bottom line is if you have surplus of a stat (defence) adding in more avoidance is useful on heavy hitters, but given the way is going, especially from T7-T8 banking Stam is pretty sensible, and dropping a couple of tanky pieces for on a threat set won't hurt either. Naxx in itself is pretty simple to gear for at a farm level with heroics, T7 and raid content. Cover that and the rest is pretty simple, until Sarth 2d/3d and T8, where threat (depending on role) and stam become much more critical.
Edit comment below is what I was hinting at, additionally with diminishing returns on avoidance moving a few pieces of gear around, using purple gems and adding on the stam will benefit later on with harder and latest content.
