transfer pizza onto stone without sticking
I've worked as a pizza cook, so I can give you a hard-earned answer. Cornmeal, and plenty of it. If you aren't putting cornmeal (or flour, but cornmeal works better) on the peel before you put the pizza on it, start. If you are putting it on, use more. Then put the pizza on it and give it a shake and make sure the pizza is loose before you try to shove it in the oven. If it isn't, lift up the edge that is stuck and sprinkle more cornmeal under it, then try again. The pizza should be completely free-moving on the peel before you try to transfer it to the oven.
