Welcome to the commuting gang. Here are a couple of other places we hang out.
http://www.bikejournal.com (look for "how was your commute today")

When you upgrade be very sure of what you want. I almost bought a carbon fiber, lightweight, 700x23 tire racing bike. Someone asked my why I wanted to start racing.
A good touring bike will fill just about every type of riding us non racers would ever do.
Fuji, trek, Novaro, Surly are examples of companies who make great tourning bikes that are also perfect for commuting, club rides, etc. Be sure to look at them when you are shopping.
I occasionally do business in the triangle area and rent a bike in Durham center in stead of renting a car.
