You don't mention what size engine you have, so I don't know if you have a 5 speed or 6 speed tranny. What I do know is I have a 6 speed trans, which uses a hydrolic clutch (and I assume the 5 speed is the same way).

1. check fluid level in clutch resivor (on firewall near brake booster)
2. if your out of fluid I'd first put fluid in & bleed the system (I use a mighty vac to bleed the system from the top) I use the vac to push fluid down into the hose thru the resivor, then the vacume side to remove air. push fluid first as this will make the cylinder that attaches to the clutch pedal open and allow the air in the system to escape.
3. if your car is leaking fluid most likely its the slave cylinder that has gone bad inside the trans bell housing. see how fast the fluid leaks, its a big job & requires you to drop the transmission out of the car. if you have to replace it I've been told you should replace the clutch cylinder on the firewall at the same time, might not hurt to check out the clutch too while its apart.

hope this will atleast get you back on the road for a while.

I just re-read your post, clutch hard to push doesn't match what im talking about, that should make the pedal push real easy ... check the hose that enters the bell housing of the trans (hydrolic line), maybe it somehow came apart & fluid will no longer flow from the clutch cylinder to the slave cylinder (in the bell housing). Nothing else makes sense, if it was a trans issue the clutch would feel normal, even though sticking in gear is a symptom of a bad syncro in a trans, its also a symptom of the clutch not disengaging. my last guess would be a bad clutch cylinder on the firewall (resivor, cylinder & hoses all one piece thru the GM dealer).
