You do not have to exit your car unless you are under arrest. It's wise to exit the car to avoid a confrentation but it's perfectly legal to stay in your car if you are not under arrest.

This was a big issue when a serial killer was posing a police officer ordering people to get out of their car, and when they did he kidnapped them. You have to get out of your car is a cop shows that he's a police officer and orders you to get out if you are under arrest. 

Again, you should get out of the car but she was in her right not to as there was no reason to. 

In Pennsylvania v. Mimms, the Supreme Court ruled that an officer may order you to leave your vehicle during a routine traffic stop and does not need to give a reason. As it is a lawfull order, you must comply or you will be breaking the law.

This has already been explained in more detail elsewhere. Do you have any proof to back up your points or are you simply asserting? If there is some jurisdictional provisor or alternate interpretation then I will concede, but it seems the consensus is that yes, she did have to get out of the car and yes, he was allowed to use force to make her if she didn't comply.
