And Policar, tripods are very useful in many applications. I don't know where you're getting the "of little use" part but even with IS I find that I often need a tripod or monopod when using heavy teles.
I don't believe that is in the context that the OP would be using them - since even a 70-200 or so is not a particularly heavy telephoto zoom, and the heavy telephotos are very expensive.
However, I do agree that tripods are still useful, especially for fashion/people photos. I tend to use multiple flashes a lot and a camera on a tripod with a wireless remote trigger, and the camera controlling the group of flashes.
Bokeh (or depth of field blur) is one of the nicest things to play around with, especially in portrature. You can achieve some lovely effects with that - and it really helps to highlight your subject and separate them from the background.
And after that, flash-photography at night with reverse-sync is another nice one to learn, especially against a cityscape background with lots of DOF-blurred lights.
