Denied unemployment, how do I appeal? - what worked for you?

I was told my separation was for misconduct, which is not what happened. I worked as a web developer before this. My employer's version of events does not match mine, and I have emails that show it. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it 14 months ago, and it settled down once I kept a simple log of every call and form.
