Tom,
Great to hear from you! Ask any questions you want, you probably know I love talking biking. My biking is going well, although the weather is keeping me inside. I have been going to spinning classes pretty regularly to stay/get in shape.
Since I am now spending spring break/summer break in Utah, I am biking a lot out there, and , yes, it is real different than around here. Much tougher but more fun, too.
As for Will's biking... He has a couple of real nice bikes.
Make sure to carry spare tubes, and either a small frame pump or a co2 cartridge system. I personally prefer the cartridges since it takes no effort to inflate the tire after a flat. Also make sure to get tire irons to remove the tire if it flats. Walking home is no fun. I also carry a small patch kit in case of a worst case scenario. I prefer a Camelback for hydration, but I do pretty long rides and take bottles and a Camelback on most rides.
I know you won't overdo it on rides to begin with, but once you get in biking shape you will be glad you live on a hill. The only thing as good as doing hill climbs and repeats is to do sprint intervals. Of course if you are just riding for fun, the hill can be a pain. Do you wear cycling gloves? They are nice to prevent numbness and if you happen to fall they protect your hands.
If you want a good online source of information, try searching for Harris Cyclery or sheldon brown. There is some excellent information there. Online sources of bicycle equipment are www.performancebike.com or www.bikenashbar.com.

Do you have a bike computer? I personally would never ride without one. You can go cheap or expensive depending on what you want. I have a Garmin gps bike computer. I think it is called an Edge 305.
www.sheldonbrown.com is the website for his info. He just recently passed away, but the information is great.
