I generally try and keep ISO as low as possible for quality, whack the flashguns up high, use a shutter-speed as low as I can get away with, and then just vary exposure brightness with the aperture, as most things are in focus anyway after f11. I always shoot in RAW, to give as much latitude for post - it seems a lot easier to bring dark shadows up to usable, than to bring highlights down, so I'm not too upset if it looks a bit underexposed on-camera. Over-exposed highlights are so depressing if you wanted to keep the detail there.
That said, Adobe Camera RAW is currently a nightmare for me with a NVidia graphics card - last two versions have just crashed constantly whenever I'm working on a RAW image, but fine once exported to a 8-bit image. Adobe still not saying much, but there's clearly a problem as it's not just me moaning.
