throwout bearing squealing?

yeah it sounds like the TOB. Mines a bit noisy in the SVO and does as you've described. I don't think you can actually lubricate the bearing inside the TOB race by shooting lithium at it from the clutch fork opening. And you might get some splash on your clutch pressure plate so be careful trying that.
You'll probably need to break down and do a 2 hour job dropping the tranny, replacing the bearing, lifting it back in. It's not hard at all.

my throwout bearing is chirping too. the way i see it, its not hurting anything, and its not bothering me too much so its staying in the car

I just replaced mine last week, quiet as can be(besides the power steering and ticking lifter(s) ). When u do the change, make sure to grease everything except the clutch and flywheel or else your gonna be back there real soon.

Everything includes the main shaft where the bearing resides and teh little swivle ball deal that the fork balances on. Also , to get the fork out you hafta remove the linkage from it...
Tip: when you put it back make sure everything is taunt (IE:the little metal ball at the end of the cable in its holder) before you try to connect clutch cable.

on my old 2.3 I forgot to lube the front bearing retainer and the TOB was chattering on it... spraying it with some lube helped, but then i started having to do it like every oil change... annoying as hell...

Fix that SOB TOB, mine went out and it did damage to the fingers to my clutch, don't wait too long mine exploded. Bad news
