When I'm composing the picture it looks like the picture will come out all grainy because of this. Yet it doesn't.

I'm so bothered by this...
What you are seeing is the Fresnel lens pattern that is etched onto the bottom surface of your focus screen. It is normal. Set your aperture to f/8, point the camera at the sky and use the optical DOF preview to stop the lens down. That should allow you to clearly see the source of your smudges.
