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?

1. Yes, and it is glorious. Although by the time he DOES get his comeuppance, you'll hate him a LOT more than you currently do.

2. I don't think it's ever mentioned how many legs they have, but I think they do have forelegs.

Up to book four, they do not talk. There is also no record of any dragon ever talking to anyone, so I don't think they'll be doing any talking.
