As mentioned already, the Bracers of Armor and the actual armor don't stack since they're both an armor bonus to AC. Mage Armor likewise does not stack with either the bracers or the full plate because it too is an armor bonus though since it's a force effect it would grant that bonus against incorporeal attacks, unlike normal full plate. And finally, Inertial Armor is also an armor bonus and the power itself explicitly says it doesn't stack with regular armor, but like Mage Armor it would protect against incorporeal attacks.
Did you actually read the rules for all those effects before letting them stack? As per the normal rules, they definitely don't.
As for the discussion about Defending, one can argue that the wording "stacks will all others" means it stacks with everything other than itself. Even if the players don't interpret it that way, that's almost certainly exactly what the designers intended it to be because it stacking with itself is nonsensical and could very well become broken. Note that it can be applied to shuriken, and since they're enhanced as ammunition it would be relatively cheap to get 50 of them (since 50 of them at +5, or technically +6 for defending) costs the same as a single +6 regular weapon, and stack all of them for a +250 AC boost.
I mentioned in another thread that I have very little experience with psions or psychic warriors, the little info I do have really is from the DnD Tactics game on the PSP, in which all these things are allowed to stack. I'll have to get the book off the player and check this. As a side question, would bracers of armour stack with armour that doesn't have bracers inbuilt?
