I'd be interested in this too and would be willing to chipin a bounty for this.

I would also need the features listed about as well as:

an admin side attendance list that one could print out and bring to the event and check off the people that either reserved tickets to pay at the box office or have been marked as paid as paying through paypal or marked as paid because they are a season ticket holder (season ticket holder would be a role, so maybe that would go with different prices per role).

Thanks,
