I disagree. Issues between players should not be worked out between characters. Resolving player issues by in-game proxy is kind of the definition of passive-aggressive, and negative reinforcement (swatting someone with a rolled-up newspaper when they do something wrong, f'rex) is not a reliable training technique.
It's not an issue between players, it's an issue between characters, if I understood correctly (referring to problem #2). The issue is that the problem player's PC is doing things IC that are problematic for the other PCs. It would totally be appropriate for the other PCs to respond to his IC actions with IC actions of their own.
