First things first, your focus needs some work, the previous suggestions will work, but if you still have trouble focusing, then just pick something bright a long way away, anything more than 50 m should be fine. Then take off the autofocus. If you then shoot a couple of stops in from maximum aperture you should be fine.
The rainbow thing looks like a bright light source off camera, use a lens hood, this should help, if you're already using one some sort of shield from the light (or moving the camera) would also help. Set the camera up in a different position and see if you move the rainbow, that'll confirm it's a light source.
