You should immediately consult privately with a lawyer who practices in the area of employment law or civil litigation. The statute of limitations for some torts--such as assault and battery--is only one year. One the year passes, you can't sue via those causes of action.
Many lawyers offer free initial consultations. Make a few calls, visit a few lawyers, and decide whether you wish to pursue things legally.
I have used Facebook messages as evidence in the past. To get them into the record, a lawyer only needs to call the alleged sender of the message as a witness and then ask them to admit to sending said message. There is a little bit more to it than this--the Rules of Evidence struggle to keep up with the rapid development of technology--, so I suggest you speak with and hire a lawyer.
You should privately speak with a criminal defense attorney. They can help devise a defense strategy for your daughter. You should refrain from posting material online or speaking about it with non-lawyers, because what you say may be able to be used by the prosecutor.
Take pictures of your daughter's injuries and save everything for her lawyer.

You should consult privately with a lawyer who practices in the area of open records act requests. The crime lab file is arguably an open record, but they likely would redact portions of it due to privacy concerns that are established by law.
Open records act requests are quite fun to do--I've made it a hobby. You never know what kind of buried treasure you will find.
There are a number of choices here: (1) petitioning the Ohio Supreme Court for review, (2) possibly filing a lawsuit against your former attorney for legal malpractice, and (3) possibly filing a grievance against your former attorney. You should privately speak with an attorney to figure out which course of action(s) is/are best to take.
Good for you for filing an open records act request. A lot of citizens don’t know how to do those. One episode of Forensic Files on TV depicted a story...
