Using your Evans dB One tom heads is easy. Just mount them on your drums as you would with regular drumheads. When you practice, you'll notice you can play quietly without sacrificing the sound quality. As for precautions, avoid hitting the drumheads too hard with sharp objects as this could damage the mesh. To maintain them, use a soft, dry cloth to gently wipe the drumheads after each use. This will keep them clean and in good condition for a long time.
