Sandman, personally I'm much more intrigued by you hearing that Collins and the Packers are working towards a deal that'll pay him good.... he deserves to get paid! Good news, to say the least.
As for Charles... I can understand if he were upset with his contract. From the sounds of players, Charles has been an unquestioned leader for the youngsters on this team.
Collins and Bigby have both talked mentioned the influence Charles' work-ethic has had on them. I believe a couple of years back Collins credit Charles with 'taking him under his wing' so to speak to become better at preparing for games off-field to have more success on it.
Last year, even Brad Jones said that when he was inserted into OLB to replace Kampman, it was Charles who let him know that he (C-Wood) had faith in him (Jones) to deliver and keep the defense rolling.
If Charles is unhappy, I don't worry too much becuase I'm certain the Packers will take care of him. For what it is worth, I don't think Charles needs to be given a new contract to satisfy him.
For the past three years, Driver's current contract has been re-worked so that he could get money without adding on extra years. I don't see why this couldn't be the case with Charles, either; dude has been stellar.
