1) Probably nothing. I hate big crowds anyway
2) I'd try to tell her that I still think she's beautiful. Let her feel a little good in her horrible moment
3) I hope I don't die
4) No, I'd rather not have a kingsguard hacking into me (and everyone knows how eager Joffrey is to yell "off with his head")
If I lived in Westeros, I would go to the citadel in Oldtown and teach them all some advanced mathematics and physics. Given what I know right now, I could put myself in Westeros' history as their Newton, Laplace, Euler, Maxwell, Einstein (if I even get as far as relativity) all in one. I would even write some other secret tomes on advanced topics that they will never reach while I'm alive, but that they can uncover later and use to bolster their knowledge (such as advanced quantum mechanics, quantum field theory, general relativity, etc).
