As far as equipment goes, street photography, by its very nature, includes many ephemeral opportunities. Forget tripods and stuffed gadget bags full of little goodies. It comes down to just you and a camera. Set up your camera so that you'll have a minimum of fussing around with settings. Learn to be inconspicuous [or carry a pad of model releases . . .].
Lighting is important. Bright, sunny days lead to contrasty prints and deep shadows. That can be a problem. Eliminate it by choosing hazy or cloudy days. The range of fl's of your camera are more than sufficient, as is the maximum speed. The rest is a matter of training your eye to see.
Street photography at its best is high adventure. There are truly great pictures out there. Your job is to find them. Enjoy the thrill of the chase.
