What is adequate disciplinary action for simple assault in college?

I am a junior in college in TN. Last week, my roommate and I got in an argument then she attacked and assaulted me. She grabbed and squeezed the base of my neck, twisted my hands, and scratched my arms. and I requested her to "get her hands off me" 13 times before I pushed her in self defense. She attempted to seize my phone, and block my exit from the room. I recorded much of the attack which proved my innocence and lack of initiation. The dean didn't want me to report it to campus safety immediately so I didn't. But later I did. They submitted the case to the discipline committee. My questions are: What is the standard disciplinary action for an assault like this? Can I as the victim be notified of the disciplinary action taken? (my dean informed me that I couldn't know what actions the discipline committee took)? Can I press charges against her? Can she cover the costs for a diagnosis on my laptop? Can I take out a restraining order on her?
