The release part is easy -- just press the shutter button on the end of the release. I usually have a hand on the monopod and perhaps another on the lens, but, when shooting fast action sports that is not always possible and anything goes. In those situations I have a second body on my left with a shorter zoom, usually a 70-200/f2.8. My shutter speed is normally 1/1000th or better so rock solid isn't absolutely necessary. I do something completely different for other types of work. It all depends. I've developed a work habit and workflow over a good number of years. Check out my SmugMug site to see if you like my work. Best of luck.
