It's important to note that neither of the things that you mentioned is actually a "feat". Iron Fist and Whirling Defense are both *powers*.

Also, "psionic" isn't a damage type. It's a power source, which is a completely different thing. A lot of psionic attacks will tend to deal psychic damage *but only* if they specifically state that they deal psychic damage, which neither of the powers that you reference here do (they both deal untyped damage).
