If you want a studio setup, Justin posted one a little while back. I can't find it, but there's a great tutorial here
If you want to simulate natural light, start with where the light is coming from. Don't add too many sources because it will screw up your shadows and indirect lighting.
There is generally one key light source, with the rest being bounced around the scene. Your scene has washed out all the shadows on your model, your object looks like it is floating in space. Because of all the light bouncing around the scene, you have actually washed out the shadows.
If you would expect your scene to be illuminated by light fittings, add the fittings, or add small (think of the size of the fitting) LEMs to simulate them. Then you might want to add a large low power LEM behind the camera to simulate a camera flash - only if you need it!
Personally I would take out the wall washing LEMs. They are killing your lighting generally.
This is about scene setup, not lighting not working 😉
