I agree about the pilot bearing, although they can be difficult to
remove.  If your clutch disk has any signs of oil having contacted it,
replace it.  It is a good idea to replace the clutch disc every time,
but I just wanted to point out that it is not always necessary if you
are on a tight budget.  When I rebuilt the engine in my bus 4 years
ago, I looked at the clutch disc and decided it looked purty good.  Put
it back in, along with the original pressure plate and throwout bearing,
and have driven it another 30,000 miles with no problems at all.  When
I pulled the engine last weekend, the clutch still looked good.

Another data point - My Mustang.  Last year I pulled the tranny to put
in a new clutch.  Replaced the disc, pressure plate, throwout bearing,
and pilot bearing, as the tranny is not easy to get out and I didn't
want to have to do it again soon.  With all new parts, I was guaranteed
not to have any clutch problems for a long time, right?  Wrong.  As soon
as I started it up, there came a noticable squealing from the throwout
bearing.  The old one had not squealed.  For six months I have put up
with that squeal, which goes away when I depress the clutch.  Last
time I was at the drag strip, after the first pass it was squealing a
lot louder, and the sound had changed to a slightly more grating kind
of noise.  I know I am going to have to pull the transmission again
soon, and it p*sses me off.  I should have left the old throwout 
bearing alone, but everyone always recommends replacing it every time,
because "It's only 20 bucks".  But it's not.  It's 20 bucks, plus
labor to pull the tranny a second time and another 20 bucks for another
throwout bearing.  And you still don't know it will be fixed.  I guess
a mathematical formula would be more appropriate - wish I had some
special fonts.  "The limit as N goes from one to infinity with
N being the number of times you have to replace the throwout bearing
before you get one that doesn't squeal, summation of N * (cost of throwout
bearing plus labor to R&R the transmission)." or something like that.
You know what I mean.

The moral of the story - "You can never be sure"

and given the above, in most cases, I ain't gonna replace what ain't broke!
YMMV.
