Clutch/throwout bearing options out of warranty

Hey folks,

New (to me) 2006 Tacoma this weekend with 68,000 miles, that's unfortunately exhibiting what I believe is the symptom of the TSB for the throwout bearing:

1) slight chirping when clutch pedal out, slightest pressure stops chirping (i.e., throwout bearing)

2) An awful lot of clutch chatter when starting out in 1st gear and occasionally when making a slow shift into 2nd gear. Almost like a groaning, chatter noise.

The clutch isn't slipping, per se, but I believe the combination of those two symptoms seems to me that my truck is exhibiting the exact thing that would have otherwise been fixed with the TSB, if I were under warranty. Otherwise, the rest of the truck is in great shape.

So -- what are my options, here?

I could obviously just replace the throwout bearing with another one. How long until that one fails? Is there a manufacturer of the bearings that may be beter quality than some others? I know Aisin clutch assemblies tends to be much better than their LUK counterparts in our trucks. Any other options?

But if I'm going to do that (or, pay somebody to do it, depending) -- why wouldn't I just swap the whole clutch assembly out? You have to disassemble just as much to just reach the TO bearing, if I'm not mistaken.

Any recommendations on a clutch assembly? Any need to replace the flywheel as well, given the symptoms? I don't need anything terribly high performance, though quicker revving would be a nice benefit.

Considering doing the work myself -- I've never pulled a transmission out myself, but I'm willing to learn and otherwise semi-handy. I've got a buddy who's pretty Toyota savvy that would probably lend a hand. How difficult is the transmission to remove in order to change a clutch/T.O. bearing in our trucks?

Alternatively:

Anybody have any luck getting a dealer to address the issue slightly out of warranty? (I'm guessing not, but can't hurt to ask)

Thanks!
