I have only just registered but I have a partial mash under my belt that went really well. You are going to need an extra pot, anywhere from 3-5 gallons, a grain bag/paint strainer bag, and some binder clips. That's all you really need to start working from your stove. A nicer electronic thermometer or floating thermometer could be handy too. I followed this tutorial on here
to do my first PM. Try looking at your equipment versus the list there.
