My employer didn't file me correctly, what do I do?

I have worked for the same business for years. 2 months ago it was bought out by a new owner. This new owner never had me fill out a w-9 or a w-2, and she laid me off because she could not afford to pay me and the business is being run into the ground. I was going to see about applying for unemployment, so the next day I went back to her asking for her record book with my pay information and total hours p/ week which I initialed. I only recall her paying me once with a check, and the rest of the time cash. She asked me why I needed it and I told her it was for tax purposes and my lawyer needed a copy. She instantly became defensive asking if I was going to sue her. The next day she calls me leaving a voice mail asking for my ssn. I never returned her call, but did stop by later on that day to pick up something I had left. She coaxed me into the office wanting my social and for me to sign a w-9. I told her I was not about to give her any information until I hear someones LEGAL opinion. This should have been taken care of from the very beginning correct? That is the employer's full responsibility, right? Should I give her the info or just call the North Carolina Department of Revenue. BTW... she is not a trustworthy woman. She is very unprofessional and is very irresponsible with money. HELP!!
