The best way to learn in my opinion is to find a nice level parking lot and get good at starting without touching the throttle. With practice you will be smooth and relatively quick at taking off without giving the car any gas. When you get comfortable with that start adding throttle for a quicker takeoff.
Make sure that when you clutch you push it all the way to the floor and when you're not pushing it your foot isn't on it.
At a stoplight for example you want to keep the clutch all the way on the floor until you are taking off. Better yet, take the car out of gear and keep that foot on the brake.
