If Joffrey dies, then Tommen is king. When Tommen dies, Mycerlla gains the throne since Stannis is attained traitor. If Mycerlla dies, then rightfully the throne goes to Stannis Baratheon. If the Baratheons of King's Landing practice the Targaryen succession laws, then It would be Joffrey, Tommen, Stannis, Shireen then Mycerlla. If their are no Baratheons left, it would go to a distant relative of the main Baratheon branch.

Balon is screwed.

Joffrey is screwed as well. He is a bastard born of incest.
