Thanks for the advice. I was able to replace the low-beam headlamp bulbs without too much trouble. I used Osram Sylvania H7-ST Silverstar bulbs that I bought on the internet for ~$45. I had a little trouble getting the rubber boots off. It took more force than I was expecting, but eventually they popped out. Also, it takes quite a bit of force to unhook and hook the looped end of the wire that holds the bulb assembly to the headlight fixture. My one additional suggestion is to make sure you have good light. I did the job in the driveway and positioned the car so that the sun was shining in the right direction. By the way, after replacing the bulb on the passenger side so I could get the hang of it, I was able to replace the bulb on the driver's side without removing the battery.
