I would also suggest not using any references to the "VRWC". The general public thought she was a little paranoid over that, no sense suggesting flesh and blood members are actually out there. It's better if Hillary is the only one mentioning that phrase, it makes her look kooky.
One question you and the other FReepers committing their time and money to this event need to ask is what is your goal? If the goal is to put questions about her in the minds of swing voters who may be voting on her presidency one day, then attack her credibility be reminding them of her own scandals and idiocy. If the goal is to get in Hillary's face or make her "uncomfortable, than by all means throw Bill at her.
Keep in mind that the second option, while personally satisfying, might not have any long term political or strategic vale.
