Although I cannot tell you specifically what to do, I can give you some suggestions.
1) You need to wait till you receive your right to sue authorization from the DFEH (or a notice that the DFEH is pursuing a complaint on your behalf) to pursue with any legal action against your employer.
When you receive your right to sue notice, you should hire an attorney on a contingency basis to represent you, so you only have to pay the attorney if you receive a settlement or a verdict in your favor.
You can find an attorney to represent you online here:
2) In the meantime, you should definitely file for disability benefits if you haven't done so.
3) As far as the reports written by attorneys of the company, unfortunately, you are not entitled to a copy and will not receive one. In fact, if the attorney were to disclose a copy to you, he or she would have committed an ethical violation by disclosing information that is privileged between him and/or her and the company.
However, if you were somehow led to believe that the attorney was acting in your best interests (by the attorney him/her self), you could file your own complaint with the bar or malpractice action against the attorney.
