Welcome, welcome, welcome, Ovenator! Good of you to join us here at SimV!
There is deffinitely a program that can remove the gauges that aren't being used, but there really isn't any reason. Unless you are worried about disk space, they aren't doing anything but just sitting there. They don't take up memory while you are flying, as they are dormant unless they are on the panel you are using at that very moment.
An added bonus of having a large gauge compliment is that if you ever get into panel design, it gives you a large range of gauges to choose from, instead of the boring ol' stock ones.
If you still want to remove them, though, here is the link to the utilities section of FS2002. I'm not sure whether or not this will remove the new XML gauges sets for 2k4, as it was designed with FS2k2 in mind, but you could try it. 6th one down:
