Lots of good comments (meaning I agree with you). A few quick responses:

"Although, I vaguely remember Tyrion killing him with a sword not a crossbow?"

Nope, crossbow.

"I thought the Hound resurfaced later with Stoneheart's group?"

The book is ambiguous. Most readers think he's alive, but not with Stoneheart.

"I think Jojen does die but I can't remember how exactly."

He's still alive at the end of ADWD, but he's clearly dying. The show just moved it up.

"I thought he turned her down in the books"

He did.
