Clip pedals are great, even on a hybrid, and they really do give you extra power, even though you are bound to fall out of them the first couple of times you ride. I have mountain bike pedals/shoes (and shimano sandals) for both my hybrid and my road bike -- the cleats (the metal bits that clip into the pedals) are recessed a little, so you don't teeter too much when you walk, and you get less wear on the cleats. There are lots of discussions on what sort of pedal to use -- search the road forum for clues -- but if you are commuting in traffic you want something that you can click out of in a hurry, and you want it to become second nature to click in and out. Have fun.
