No, you don't. You're also lacking:
5% damage debuff (for 15 sec)
Ion Cylinder damage proc and movement debuff
Damage mitigation via shields...doesn't affect much in PvP, but it does help
Most likely reduced HP compared to a full spec tank
I see you are trying to make a list of advantages as shield tech over this AP spec switcheroo, but I'm a bit confused in your direction and am worried maybe you are assuming a bit too much. He might have the 5% dmg debuff in his build. It could be possible he has the armor increase as well (not that I would advocate that). Additionally, you didn't recommend the OP make any changes to his build outside of Iron Fist > Advanced Tools. That would leave him without Neural Overload, which you just advocated as an advantage over the AP cylinder switcher.
The answer you wanted to give to the OP for #1 was No, but if you do X,Y, and Z you can ...
