I think the throw out bearing is bad, how can I tell?

I started hearing a noise that sounds like an engine rod knocking.
The noise seems to be tied to the clutch operation. From under the truck, it seems to be coming from bell housing. When the clutch pedal is released in neutral, it begins. When driving in any gear the sound is not noticeable until you coast in gear. It appears to match the engine speed.
I have never heard a bad throw out bearing so I'm thinking this is it.
The sound is loudest when coasting in gear.
I did have a problem last week when it got stuck in 3rd gear. I had to really force it out hard to get to neutral. I thought the reason that happened was I shifted pretty fast around a corner from 5th to 3rd. I have no idea if that would have cause that, but that is what I did when it got stuck.
Can anyone school me on a bad throw out bearing or what the noise might be? I do know it is not a piston rod, and it reacts to the clutch operation.
Thanks,
