I *really* suggest that you start reading the stickies at the top of the Newbies Corner, especially the photography notes for newbies.

Or find the book 'Exposure' by Bryan Peterson .. either in the library or at the book stores.

I can sympathise with your feelings , and I take it you are seeking confirmation on your understanding.

To make things simplier , Shutter speed and Aperture and iso controls exposure. Speed of shutter controls motion , aperture controls DOF. So your understanding is generally correct.

Just read more online literature on exposure and the sticky posted by fellow CS members and you will be fine !

Simply put.

Slow shutter speed can affect the picture in terms of motion. With a moving subject, you'll not be able to capture it clearly or it you are not able to hand-hold al lower shutter speeds.

With a faster shutter speed, you'd be able to freeze the subject.

DOF, larger aperture will give you shallow DOF, smaller aperture will give you more DOF. This is generally speaking and you'd have to consider the other factors like subject to camera distance as well as background to subject distance.

Remember that by "larger" zac08 means lower f number, for example
f1:1.8 is a larger larger hole in the diaphragm than f1:22

There is always a trade-off. There is a certain "amount of light" that your camera requires for correct exposure at any given ISO setting.

You can reduce the amount of light required by increasing ISO but at a cost of having more distortion and noise.

If you increase DoF by choosing a smaller aperture hole then you must increase the duration that the shutter is open for, at a cost of having more blur from motion.

If you increase shutter speed to freeze action then there is a cost of less DoF so your focus becomes more critical
