Adding a tiny variety in timing on MIDI notes isn't worth it to me, but I suspect SD2 may actually add subtle delays to some hits if that particular feature is turned on (the descriptions are a bit vague, so I'm not entirely sure which one it is, if any).
On the hi hat, for example, it sounds a lot more convincing if you alternate between a harder and a softer hit. For metal and a lot of rock, you can get away with a constant velocity on the kick and the snare for accents. For fills, you'll need a bit more variety for it to sound natural. Low-velocity ghost notes can really help the drums sound alive. Be aware of the difference between 16th beats and 24th beats. For the longest time, I wasn't consciously aware of the difference and had issues programming the grooves I heard in my head.
Take a look at some of the stock MIDI grooves. It may give you a few good ideas.
