Determining f-stop really depends on the feel you want for your photo and is more of a tool on how creative you want to be with your subject and composition.
Large aperture will give you a shallow DOF and throw the background out of focus relative to your subject. Keep in mind that there are things that affect your DOF as well such as lens focal length and your distance to the subject. The longer the focal length and closer you are to the subject, the shallower your DOF and vice versa.
That being said, if you're trying to isolate your subject, go with a larger aperture. An example of this would be if you're taking a portrait or taking a photo of something.
If you're doing a landscape or a scenic photograph and you want everything to be in focus, you should stop down and use a smaller aperture. F8 usually works and is usually the "sweet spot" of the lens where everything is sharpest and you eliminate flaws in the glass such as vignetting and chromatic aberrations.
However, these are just general rules or tips. Again, it all depends on what you want to achieve with your photo.
As for settings in AV, again, it depends. For me, I do a lot of portraits so I'll usually stop my lens down to about 2.0 on my 85mm to get enough DOF so that the whole face is in focus, throw it on spot meter, meter for proper exposure on the face, lock the exposure in place, focus on the eyes then recompose and take the shot.
If that didn't make any sense to you, read up on your camera manual.
