It seems strange that armor kits wouldn't give armor to anyone but tanks, I suspect that's a bug. It is of course only supposed to give AP from bonus armor to tanks, but to not give its actual armor value seems dumb. Well I'll send Bliz a note and see what they say.
You're confusing armor with bonus armor. Armor is the base value on chest, gloves, boots, legs, wrist, helm, shoulders and shield only. ANY other armor values are bonus armor (eg rings, weapons, enchants, armor kits, elixirs etc).
Blizzard has stated (sorry I don't have a quote for you) that bonus armor is only for tanks. Bonus armor does not even show up on non-tank character stats the same way that spirit does not show up for prot warriors.
