My new Trek 1000 has a type of valve stem different from the standard (car type) stem on my mountain bike. Do I need an adaptor to fit it to a pump or do I need a whole new pump? Also, have you seen a tire gauge that fits this stem type?

You can buy a little adaptor that screws onto the valve stem so that you can use your present pump and gauge with this type of stem. The adaptors cost about $1 or so. Get two because if you're like me, you'll lose one.
These are definately called presta valves. I just bought a trek 6000 MTB and they have the same deal. be careful when you're pumping them using a hand pump as the valve can seperate from the tube causing a very annoying deflation. I'm yet to work out the best way to avoid this (happened to me again this morning), so it's worth carrying a spare tube just in case.
