Over the weekend, I discovered that the plugs in the other cylinders had started to gain some black deposits. I'm not sure if they were fuel or oil. Late at night, I warmed up the car and headed out to a nearby intersection which leads directly onto a freeway that has about a mile or so of straight road (basically, a nice place to do a little "drag racing"). I gave the gas pedal a good push and saw a nice cloud of smoke come out the back. I kept my foot down until I reached the legal speed limit - a neck breaking 10 seconds or so and then drove around at that speed for around 20 miles (I did not do the full "italian tune-up").

I pulled the plugs again after the engine had cooled down and found that the plugs from the back 5 cylinders had burned off most of the deposits and were now tan in color, and that the plug from cylinder #1 had burned some off as well, leaving it cleaner than how it was before I started the run.

The only great outcome of this is that I no longer have to get out the dremel with the wire brush to clean the plugs . I'm going to do more driving around with the known good wire from the old set in cylinder #1 and see if that affects anything.

Since the other plugs also started to foul a little, could it be possible that I have a coil that is starting to go? I'm willing to try out that accel coil that was mentioned sometime back on the forums if it would make any sense to do so.
