I use Continental grand prix 4 season tires. They grip the road really well and give a comfortable ride. They are a little more expensive than some, but seem to get less punctures - fair trade in my book! Skinny tires come in different widths, believe it or not. Try to stay away from really skinny tires with little or no tread.

Is there another LBS in another town that you can get to easily? I hate being dissed by snooty little boys in bike shops. They lose my business really fast.
