CHEVY POSSIBLE THROW-OUT BEARING REPLACEMENT?

1989 Chevrolet Truck

Transmission problem
1989 Chevy Truck V8 Four Wheel Drive Manual 41,640 miles

With the engine running, the truck makes a quick-paced rhythmic squeak when the clutch pedal is not depressed. The slightest depression of the pedal silences it. I've had 2 people already tell me it's the throw out bearing, and since this is the third clutch on the truck, it is possible the old bearing was used in one of the repairs. I guess my real question is, if it is the throw-out bearing that needs to be replaced, how difficult is it to do, and how is it done? I have moderate mechanical skills, but I am no expert.
