You are thinking correctly, headpiece shouldn't be shared, it's hundreds of dps loss. All others can be used successfully, but the key rule is tank survivability > kitty dps.
Shoulders - Shifting Dreadstone and PvP enchant (small dps decrease)
Hands - same gem, agility enchant (virtually no dps decrease).
Legs - 2xStamina, tank enchant.
Chest - bears don't use this piece thus no dilemma.
// Total dps loss should be about 2% at most.
For bear, the decision is easy - 264 ship chest, the rest 4xt10. For cat you must change the headpiece, so either get tier chest and offtier head from raiding, or buy second t10 head and aim for offtier chest/hands.
