* Smaug didn't like them thumping their barrels.
* Bilbo in being clever about who he was claimed to be 'barrel rider' in reference to his journey down the river in a barrel. Smaug took this to mean he was one of the Lake-men and vowed revenge for Bilbo's intrusion into his lair.
It was Bilbo's fault. He talked about the barrels in the riddles to Smaug, and Smaug made the assumption they must have helped the dwarves escape.
It is pretty much Bilbo's fault. Not only did he taunt Smaug, he stole some treasure and the dragon went into a rage.
He knew that they had to have helped the dwarves. The clues Bilbo gave him made it clear that Laketown was involved.
The Hobbit is fairly linear. There are a few places where the time line backs up, particularly when the dwarves and Bilbo are exploring Smaug's den and Smaug is attacking Laketown.
It was destroyed by Smaug. What wasn't burned by his fiery breath was crushed when he fell on it.

Smaug is the dragon that has laid waste to the Lonely Mountain and terrorized Laketown for many years. He stole the dwarves' treasure that lived in the Lonely Mountain.
