(12/24/2003) - My battery has been dead for the past several days.  After testing the system out, I found that the alternator itself was fine, but the voltage regulator was bad.  I pulled it apart and tried to tweak it a bit, but I wasn't able to fix it.  

It was time to add a bit more juice to be able to support all my electrical accessories  (power windows, power locks, gauges, stereo, alarm, lights, etc) anyway, so I went ahead and bought this 95 amp alternator (internally regulated) from so. cal.  Then I also added the pulley with the fan integrated on the backside to help keep it cool:

Installation was pretty simple.  Its mostly a "one wire hookup" straight to the battery.  Then I was able to get rid of the voltage regulator under my back seat.  This fixed my problem, and now allows me a little more 'overhead' for future electronics.
