| What is ISO and what would be the best setting for taking action shots, in particular skateboarding. I guessed 400 but i am probably wrong. |

High shutter speeds are required for freezing the action, hence you may need to up the iso to get those speeds. For quality the lower the iso the better, to avoid noise especially.
Hope this helps,
Paul.
p.s. Look at iso as the sensitivity to light, the higher the iso the more sensitive, but also more noisy or grainy it becomes.

hmm. i dont think it's really a question of what iso, but what shutter speed. so if you are able to force the flash out of your camera, you'll be allowed to shoot at a faster shutter speed. also shooting in daylight would help. later afternoon/night could be difficult without some sort of lighting setup

It's not quite that straightforward IMO.
IF you are talking skateboarders in a skate park outside on a sunny day, you can do ISO 100 or 200 with a fast shutter speed and no flash. So you get quality and speed.
But if you are in an indoor venue and can't use a flash you might have to hit a 400 or 800, but even then it also depends on how fast your lens is. You also have to consider the effect you want (clear stop motion vs some motion blur).

Yes you can. Read your manual. That camera has Aperture Priority, Manual Exposure, Shutter Priority. The shutter speed can be controlled in any of those settings. |

In Aperture Priority the shutter speed is "controlled" indirectly; in the other modes you can set the shutter speed value directly. |

you have quite a sophisticated piece of equipment.
I would take a look at the instruction, as IGeneralE suggested...

The Sony DSC-P73 has neither shutter priority nor aperture priority modes, but it does have a full manual mode where you can adjust both shutter speed and aperture independently of each other. I presume (but haven't ahndled the camera so can't be sure) that there will be an exposure "bar" showing over or underexposure as you make the adjustments. Your ISO can be set to 100, 200, or 400.
Your desired shutter speed, basically, is as fast as you can set it and still get correct exposure. The camera will go as fast as 1/1000 sec. If the action is coming towards you or going away from you you can get away with a slower shutter speed; if it's crossing the plane of the image from one side to the other you need a faster shutter speed to freeze it. 1/250 should be adequate for skateboarding in most cases, and 1/125 might suffice. If you're shooting jumpers, try to capture them at the apex of the jump before they start coming down; they're basically frozen still in space for an instant and motion is much less of a problem then.
It looks as if your flash is not powerful enough to be of any use, unless you are really up close and personal with the skaters.
Robt.
