ASoIaF (questions and spoilers)

I'm about halfway through A Clash of Kings, and I have two questions I must know the answers to:

Does Joffrey ever get any sort of comeuppance? 'Cause he's a total bastard.

Do the dragons in this series have forelegs or are they like wyverns and do they talk eventually?

That makes me disappointed, I like Daenerys. I also hear that Tyrion isn't in the fourth book, which also disappoints me because he's the only Lannister (thus far) that I think isn't a douche bag.

That said, I don't really hate Tywin yet; he hasn't really done anything too terrible. I used to have a great disliking for Cersei and Jaime, but I understand some of their motivation so I can't hate them as much.

There are actually a lot of characters I dislike so far, actually. But in cases like Sansa, more so the first book, she's not so much of an idiot anymore, but the fact that she still blames Arya for what happened to Lady makes me want to see Littlefinger or Sandor Clegane rape her. Stannis is an idiot, too.
