Even your basic point and shoot camera has most of the same controls these days.
1) The aperture is just that, in your picture, the aperture is hexagonal opening where you can see the reflection of the photographer. F-stop is just the measurement of the aperture.
The lower the number, the larger the opening, the greater the amount of light, and the shallower the depth of field. For instance, f/2.4 lets in a lot of light, and gives you a very shallow depth of field, where f/16 lets in a little light, and gives you a wider depth of field.
So your two major exposure adjustments are aperture and shutter speed. The shutter speed controls motion in the image, and the aperture controls depth of field. When using a flash, 1/60th is the standard shutter speed, and you can really only control the exposure with the aperture.
The SLR will still have a fully automatic mode, P will give you some more control, but it mostly automated. Shutter priority lets you choose the shutter speed, and it will choose an aperture that gets the exposure correct. Aperture priority is the opposite. Manual relies on you to set both.
ISO will control exposure time as well, but the trade off for a higher ISO is more noise. Noise is bad, always IMO. It doesn't look nice like grain can. Keep it as low as you can in your situation, and try to not pass 400 if you want to be able to print larger pictures.
