Can I take by boss to court and sue him because I shouldn't have been paid as a contractor?

I started a job two and a half years ago for a boat brokerage company. When I was hired, they never told me that I would be paid as an outside Contractor. They did not give me a choice whether I wanted to be an employee for a Contractor. When I had an accountant do my taxes last year, they told me that my employer could get in trouble for paying me as a contractor, because I wasn't really a contractor. I really needed this job so I did not confront by employer. Well now I just got laid off and because I was not allowed to contribute to my unemployment benefits because I was a contractor, I cannot collect any monies now. Everybody is telling me he could get in trouble for doing this. Second question, I moved to Florida 4 1/2 years ago and when I came here to Florida, I was collection already collecting New Jersey unemployment benefits because I didn't contribute to my unemployment insurance in Florida, can I collect from my old NJ unemployment account?
