How can I tell what the largest aperture my lens is capable of? I To get the smallest opening, you can put the lens on the camera, and adjust the aperture until you get the largest f number possible (quite often it is f22 to f32).

Is f/5.6 the most Picture would be since the expensive lens have very low f-stop Please excuse my ignorance, but I was always under the impression Sharpness though is only one reason to use different apertures. Having said all of that, I will say that using an aperture that is about halfway between the largest aperture your lens is capable of, and the smallest aperture your lens is capable of will usually result in the sharpest photo. Another good read might be "Understanding Exposure" by Bryan Peterson. I suggest you Google "understanding aperture", and you will get hundreds of articles to read. Really though, there is not enough space in a short post to describe aperture and its effects. Larger aperture numbers (smaller actual aperture opening) leave a larger depth of the photo in focus. Small aperture numbers (large aperture opening) have only a small depth of the photo that will be in focus. Aperture does affect depth of field and you need to understand that in order to use a camera effectively. The actual f-stop used does not necessarily make a photo sharper or less sharp.
