Not to discourage you. But it's more helpful to learn CONCEPTS instead of "what settings do I need"
If I tell you what the "average" settings I would use for concert photography are (which sounds close), you might get some good shots.
But you might also get some crap shots because I don't actually know what you're trying to shoot, I"m just guessing...
You should do some research on exposure, and how shutter speed, ISO, and aperture combine. And what the benefits / drawbacks of each are. And then shoot with your camera a bit to get a feel for how it works.
Basically you need a certain amount of light to hit the camera. And all three increase (or decrease) the light coming in.
Let's say you double your shutter speed. You were shooting at 1/125 a second, now you shoot at 1/60.
If the figure skaters just got on stage and are standing still, the picture will be sharp, If they're moving REALLY fast you'll get blur. If you're zoomed out to 200mm you might see significant blur (you shake the camera without realizing it and if you zoom in more it gets more blurring from just your normal body movement -- like breathing -- although you can use a tripod and mirror up mode to get rid of that)
If it's really dark, 1/60 second might not be enough. So you might decide to crank up your ISO to HI 2. Suddenly even in a dark room you'll see bright as day, but the picture will have a lot of ugly noise.
So maybe you crank the ISO back down to 1600. And you open that puppy WIIIIDE open to let in as much light as possible, and you set the shutter speed to 1/500 second, so you know there won't be any blur, right?
Well, you'll still get lots of blur (now called bokeh) if you shoot the right way.
Taking pictures can be a lot of fun, but there can also be a lot of settings to fiddle with.
The art of it is to recognize "wow she's moving fast, better use a fast shutter speed"... Or knowing which ISO you can't go over in order to avoid an acceptable level of noise.
All this requires some shooting with your camera, and getting a feel for how it works...
