Narcissistic personality disorder or antisocial personality disorder would be candidates.

The person's body would be unable to maintain homeostasis, and her body temperature would rise dangerously high.
It can be. There is a disorder called PICA where non-food objects are compulsively eaten. If a person does it only once or twice, then it would not be considered a disorder. If it is a compulsion then medical intervention should be sought out.

No because sometimes you have to speak in third person. If you always speak in third person, maybe. If someone speaks about him/herself in the third person ("he" or "she" or their name) instead of the first person ("I"), this in itself cannot be used to diagnose a personality disorder. There could be several reasons why they do it and contexts in which they do it that would not be unusual. (Examples: a parent who is used to speaking that way to a toddler; someone who does it consciously to be humorous or to deliberately distance himself from something upsetting.) However, in the presence of other signs and symptoms, it could indicate dissociation (which may be a temporary reaction and not a permanent disorder).
Many reasons- you could have eaten an onion, you could have not brushed your teeth, or you could have a disorder that features bad breath.
Typically, once a genetic disorder has been corrected in an individual through gene transfer, they would not pass the disorder on to their offspring. The corrected genes would be present in the reproductive cells and would be passed on without the genetic disorder.
Nobody can write your story for you! You must think of things that have an emotional impact for you. What things would you consider crazy if someone did them? How do crazy people talk? What things would a crazy person do? Why is this person crazy? What made him crazy in the first place? Why does he go into this room? Even crazy people have reasons. What kind of crazy? Just general weirdness and being off-the-wall, or a genuine mental disorder? If a mental disorder, what is it? How would it affect them? If general weirdness, is it deliberate? How do they react in certain circumstances? How does stress take them?
