I've got a couple questions, mostly just to pick your brain. I think your character and his tech are absolutely fascinating, and somewhat similar to a concept I have for one of my own characters. :)

First question: Can the armor absorb infinite amounts of energy or is there a limit to it? If there's a limit, how high is it and what happens when it reaches it? 

Second question: How quickly can it shift from one form of defense to another, and can it use multiple defensive forms simultaneously on different parts of its surface? (Like rubber to counter an electrical attack on its arm at the same time as a mirror to counter a laser on its chest.)

Third question: How much power can it generate for its energy weapons?
