Sounds just like mine did.....it's on it's way out. It could be a combination or one of either; the quill sleeve/TOB are going bad, meaning the quill sleeve as moved off the imput shaft of the tranny and/or the TOB is shot. The quill sleeve will move off the shaft allowing the TOB to hit the PP fingers and break them causing even more noise. This will not allow the clutch to fully disengage. This will also cause hard shifts, or the inability to get the car into gear, especially reverse and 1st.
This problem will get worse, not better....trust me. You can do the self adjust on the clutch by pullling up on the clutch pedal, but that is a temporary fix. You should hear a clicking sound.
If you are a DIY type, get the video from
www.shonutperformance.com and go from there. Lots of details on the forum heading. Here are a couple of reads:

The parts for to replace just he clutch are resonable depending on style (street, race, etc). Its paying the labor that will be the majority of the price. I give a fair estimate to DIY, including the buying a stock replacement clutch/PP, TOB, resurfacing the flywheel, buying the video, building the engine support yourself and any loose sockets you may not have to around $400 or so. You can do more or may need to anyway, like replace the subframe bushings, rear main seal, carrier gasket and other misc suspension parts. It's solely a as need basis for some of these, but recommended while doing the clutch work.
If you are at all comfortable working on your car you CAN do this yourself, in your garage or on a flat driveway in say 1 full day or maybe 2 taking your time. Otherwise the labor will be as much or more than the parts alone.
