I'm no expert, but I went through a similar situation recently. The "progressively worse" comment leads me to believe that you were slowly getting air into the system, like a fitting that wasn't tight, until you finally got so much air that the clutch wouldn't actuate enough to allow the tranny into gear. Go back and check tightness of all visible fittings. Then bleed the clutch and if you are really lucky, then your problem is fixed. If the problem is not fixed, or is fixed for a limited period of time and then returns, then you will have to pull that hydraulic slave cylinder out and check for leaks there. Are you getting any fluid coming out of the bellhousing? That is the obvious sign of a failed throwout bearing failure. Make sure you have a clutch pedal stop. It is really important with a hydraulic slave cylinder. Good luck.
