The primary thing you can do to control grain is to overexpose. When shooting negative film, overexpose by 2/3 of a stop, or by 1 full stop, then pull in down after you get your scans. Your images will show much less grain.
If you're familiar with the idea of a signal to noise ratio, think of grain as the noise in this system (which is is), and your exposed image as the signal, and it will all make sense.
Another way of thinking of it is that the film manufacturer's basically want to call the film a higher ISO than it really is so it sounds faster. Speed is not something that has to conform to scientific standards, and they are able to call it whatever they wish. In other words, 400 ISO is not necessarily 400 ISO is not necessarily 400 ISO. In the movie world, cinematographers generally shoot film at 2/3 stop higher than the official ISO rating. This is why movies shot on film generally don't look grainy.
