Just on the whole kid saying you will die no matter what you choose. I think the reason you survive even though the kid said you wouldn't is because you stop relying on your implants. In order to have enough war assets and EMS to survive you have to make mostly paragon decisions through out the ME series. In a email in ME2 Dr Choclaws (I know the spellings not right) said that you heal the nicer you are to people (paragon) and the more you push them away (Renegade) the less your body will heal. So the Boy automaticly assumes because you have so much synthetics in your body you will die but since you have been mostly paragon (in major Decisions anyway) your body no longer needs to rely on the synthetic that were originally meant to keep you alive. Hence you survive all synthetic material dying.
