Since the iPhone's battery is rated for a limited number of full charges, I was thinking that I'd just leave it plugged in most of the time so that the phone runs off of external power rather than draining the battery. This should reduce the number of times that the battery needs to be charged up, thus extending the overall life of the battery. Does this reasoning make sense or would keeping the phone plugged in actually cause more harm to the battery?

It hasn't hurt mine. The lithium-ion battery does not suffer from the memory effect of earlier batteries. However, Apple does recommend that you discharge it once a month. Here is everything you need to know about iPhone batteries" http://www.apple.com/batteries/iphone.html

Personally, I keep it connected to power in the office (a good part of the day) and in the car. That's fine, as long as you run on the battery occasionally (which is necessary as lithium-based batteries do need to be used to maintain their health).
