It MIGHT not be the clutch on the way out. I have had similar problems in the past, but not the squeaking and crunching at the same time.
For crunching, make sure that the slave cylinder and all linkages are behaving as they should.
As for the creaking... I had this very same problem last week. It sounded awful and really annoyed me - the car is currently for sale.
A quick poke under the bonnet while the wife depressed the clutch revealed the problem: a linkage on top of the clutch body was making the noise. A bit of grease and the problem was soon gone.
