Welcome to composting. You'll have fun. Learn as you go. The most serious mistake you can make is not to do it. If your goal is to get compost into the garden as soon as possible don't worry about worms because you want to make a hot pile.
Worms come miraculously when the pile cools down.
May your compost be the color of coal and fluffy as down. The worms will come to the pile when the environment within is favorable to them. They require an environment rich in micro-organisms but cool in temperature. Don't worry about the worms. Yes, bread, rice and nuts will decompose.
