If you find something more you could use the Tommy and Gina story (as I can remember they are based on two people Richie and Jon used to know).
Maybe some songs like undivided about sep 11. Ya know, that really shocked them and then they wanted to be more optimistic. I can't remember where it was but once Jon said that everyday expresses that you should find something to live for because after sep 11 he noticed that life can be shorter than you would have thought.
You could also take apart the solo albums and make comparisms with the band albums. I'm sure that's a topic you can much talk about.
I think you can also find something interesting in the drycounty archives. I hope you'll find what you need.
