Dance photography is my bread-and-butter and my specialty. I actually LOVE to shoot low-light, stage light with no flash.
Trying to set manual white balance is futile due to the constant changing light and changing costume colors. I simply leave it on auto w/b and meter accordingly. I shoot in manual mode and adjust exposure on every shot I take -- it's challenging but can be done as you get familiar with this type of shooting.
The hardest thing to get used to is to NOT rely on what the camera display tells you -- doesn't matter what metering mode you shoot in, the camera just doesn't "see" the subjects like you will and you often end up with over-exposed shots due to spot lighting. You have to let your experience tell you when to adjust exposure, shutter speed, aperture, and ISO.
Since I can shoot between 4-10K shots at certain dance events, I try to shoot so I don't have to do much, if any, post-production. I need to keep my workflow to an absolute minimum to make a buck. I use PhotoReflect for my ecomm and I do use a one-click batch auto-contrast in Digital Darkroom on all images, add a little sharpness for web previews and will tweak a few select shots if they are worth the time. I always shoot jpeg-fine and depending on the event will even shoot jpg-medium. It keeps the workflow moving faster when working with large amount of files. The majority of my sales are 4x6, 5x7 and 8x10. I will get the occasional 24x36 poster order and the prints look great if you use a good lab with good paper, even from these jpeg files. I never shoot RAW -- I don't have the time
I've shot with Canon 10D, 30D and 40D. Use Canon 50mm f/1.4 and 85mm f/1.8 mostly. The 50 tends to have focusing issues when shooting wider stages with subjects in back, but is great for the closer shots. The 85 is THE quintessential lens for this type of shooting. I just purchased the Canon 24mm f/1.4 L for spaces where I can get at the front of the stage, and I have both the 50 and 85 f/1.2 L's on my wish list.
Due to my style of photography, the subject matter, and the camera/lens combo I use, my camera settings are all over the place. But, here are ranges of settings I tend to work in:
ISO - between 1000-1600 (ideal is 1250)
W/B - auto
Focus - AI Servo with center AF point
Meter - center-weighted or partial
Shutter - 1/250 - 1/500 (ideal is 1/320)
Aperture - f/2.0 - 3.5 (ideal is f/3.2)
Exposure - typically underexpose -1 to -1.5 EV
