What Is the number to the left side of screen that changes from say 20 to 50, etc. when I point the camera around?

Not quite sure what you mean - I have a K-70 and K-S1 and their display are nearly identical, therefore I presume your K-50 should also be similar.

There are three large sets of number on the left side: (from the top) shutter speed; aperture; ISO. Could it be the shutter speed ("changes from 20 to 50" = changes from "1/20" to "1/50")? I don't see any other numbers changing when I pan the camera.

Once you switch to Av mode and set your Vivitar's aperture to "A", you should see the middle "aperture" setting turns blue (meaning it is active). When you turn the thumb dial (to the right of the viewfinder) you should see the aperture number change (ie you are controlling the lens aperture from the camera, not from the lens).
