Once the throwout bearing goes bad, if indeed your noise is caused by the throwout bearing, it's not something you can just live with so I'd think about how to get it replaced sooner rather than later.
Get a Luk replacement clutch kit from Dial-A-Clutch - Your LuK Clutch Kit Specialist
which includes a new throwout bearing, clutch disk, pressure plate, pilot bearing, and pilot shaft for $140 or so. Replacing a disk/throwout bearing isn't technically difficult but it's definitely an all day job if you haven't done one before. A tranny jack is darned handy for this job.
