You should simply go to Stannis and tell him about the letter. You will get positive relations with him and gain a few honour points. I think that's all there is to it.

How do I start the Old Valyria quest?

In beta 9 when you besiege or defend Torrhens square many troops run into the wall and just keep running like that. They don't climb the ladders or go to the side exit and when I tell them to follow me nothing changes.
