Mock Trial help!!?

Okay, so we have a mock trial at school, and I'm head prosecutor. I'm still drawing my case together, which I have to get done early. I've already got my line of defence, plus three affidavits, i've got all my witnesses, and i've outlined my questioning. Is there ANYTHING at ALL that I have left out? I've been working REALLY hard on this, and I think I've nailed her, but is there anything else to prepare? Also, how exactly do you file a motion?
