I'm not sure what you mean by your first question. If you mean how to check how many pictures you have left on your card, press DISP and it's the number in brackets at the bottom right hand corner of the display.
If you mean your shutter count, you would need a separate program for that. Try searching with shutter counter or actuation counter. There's no way of knowing how many shutter releases you have left, but it should last tens of thousands of releases, so I don't think you should "run out" any time soon. I think it should last something like 50 000 actuations, give or take few ten thousand releases. Wouldn't worry about this bit.
