What can I do about someone out to embarr, and discredit me to protect her friend that tried to steal money?

I knew I would be in this situation eventually because I am a 8 year board member for youth sports, with a recent member being a narsistic, bully, Julie. She lied, gossiped and belittled people all the time. I was about to break ties with the organization because we have to work closely together. Just before I left, I caught a coach (a friend of Julie) tring to steal from a fundraiser, and made her hand over the money. I sent a email to all board members so that they could keep an eye on her in the future. Julie went balistic and demanded I be kicked off the board and imediatly hand over all league items to her. I realized if I left now I would look like a liar. So I agreed to drop off the items but said I was not quitting the board. I told her to have the president contact me if i was kicked off. I forwarded all of her hatefull email responces regaurding the theft to the entire board so that they could see what I had been dealing with and to try to difuse any of the lies she would try to use to discredit me. At this point I have not heard what she is up to but everytime I see parents or even kids I have coached from the leage, they give me a wierd look and are no longer friendly. I have been told she has promissed the coach, that I will be kicked off the board, and she dosn't have to ever see me again. I also heard back to me accusations about me saying awful things about people that infact she herself said. I never thought I had it in me to face her, but here I am determined to stick this year out or never be able to leave my house in this small town again. I need to go to our first board meeting. How do I handle this situation with cl when she starts saying things like "You're just jealouse she is a better coach", "You are a liar", "You messed up this or that and you need to go"?
