If you are going to lap with sandpaper, then it needs to be wet/dry sandpaper. Regular sandpaper will release grit that can embed into the hone, causing more trouble.
If you drive for a living, you may not want to make the effort, but you would be welcome to drive to my place in Rochester MN (250 miles down I-90) for a honing lesson. Some time with the hones and microscope should help sort you out fairly quickly.
