You need to get rid of the shadows before you add them to the shot. After your merge of the VRayDiffuseFilter * VRayRawLighting, then plus the VRayShadows, which should get rid of all shadows out of the raw lighting pass.

Technically you should render the ground plane as a separate pass as when you blur the shadows you will get a halo where the teapot meets the ground because there isn't shadow under the teapot to bleed and it will give you a rim.
