➕PLEASE HELP: HOW DO I HOST A SEDER?

I've never done this before, so I'm extending my cries for help to the ListApp community.
  1. I ordered Haggadahs
    I felt A Family Haggadah II was fitting.
  2. Where do I get a Seder plate/all the stuff that goes on a Seder plate?
    Where the hell do I find a shank bone?
  3. Does anyone have a good charoset recipe or a good place to buy it?
  4. I'm thinking brisket, Matzoh ball soup, potatoes, and roasted vegetables. Any other food suggestions?
  5. Does anyone know any fun songs or games I should include?
    This is an adult Seder, but you're never too old.
