Can someone please explain the difference between the Depth of Field setting on the camera, the Digital Confusion filter, and the Depth of Field filter. How do they work together? Which are more efficient?

The Digital Confusion filter gives the best looking DOF. It also takes into account the diaphragm shape of the "camera" shooting your scene and gives the specular highlights that particular shape in the render (the way a real camera would do). It also has an Autofocus object which you can select to keep your object focused on as the camera moves throughout your scene. There are some other very useful options in the interface also.

Lightwave's DOF setting in the Camera Properties panel render an out-of-focus image by offsetting each render pass. If you render with Enhanced Medium AA, then the DOF will have 9 offsets of the image (which can be very noticeable depending on your Lens F-Stop setting). I find this to not look nearly as good as the Digital Confusion filter.

The DOF Blur image filter is a post process blur that also has few options and tends to not look very good. It tends to have a kind of 'halo' effect around the edges rather than looking like an out-of-focus object.

I think Digital confusion has trouble dealing with transparent objects, for instance 2D artwork mapped on to a plane. LW's DOF doesn't... but also doesn't look as good.
