I am afraid "can't use them well" is not a good enough description to understand what kind of problem you are having. Could you please at least show some screenshots / renders demonstrating what you are dealing with?

Sorry, but honestly I am still not sure what I am looking at. Can you explain what the problem is?

Maybe these two will help?

You are using the Zdefocus node incorrectly. The 'filter' input is the shape that the defocus areas convolve to, not the input of the depth pass. You need to channel in the ZDepth pass into the 'depth' channel. It is also a good idea to dilate the aliased zdepth pass by 1 to 2 pixels to avoid edge artefacts.
