What to do with the river?

[AtlBrvs4Life]

This was one of the last hands of a session for me. Not a good ending. I'm not sure if I played this hand well or not. I'll tell what the guy had after some responses. Sorry about the format this is in, but the hand converter wouldn't work. I tried to highlight the more important areas though.
