[V8] ISV, dashpot, and clutches

So I replaced my clutch a while back and have been wondering why it failed
after only about 70K miles.  I started noticing that I have developed a
strange technique for shifting because the engine speed does not drop for
several seconds after removing my foot from the gas.  I can't remember if
it has always done this, but I think it has.  I removed the "dashpot"
completely after adjusting it to its minimum setting and not seeing much
change.  No real change in how the RPMs dropped as far as shifting is
concerned, but there was a noticeable shock/clank to the drivetrain when
coming off the gas.  The dashpot is definitely there for a reason - so I
put it back in and at the same time put some oil in the IAC just because I
thought it would be smart.  Now, about 5 miles into my drive to work, the
ISV appears to be stuck or dead.  This makes the car surprisingly hard to
drive.  It is impossible to shift without a serious clank to the
drivetrain as I engage the clutch - unless I really rev it high, but
coming off/on the gas in gear results in a big clank every time.

Insert lots of expletives here.

btw, do the automatic cars have a dashpot?
