1996 Chevy S-10 Clutch Adjustment

The clutch slave cylinder recently went bad in my S10. I had the slave cylinder, clutch plate, flywheel and master cylinder replaced. When I got my truck back, the clutch is now very "spongy", it will not disengage unless the pedal is pressed completely to the floor and there is a tremendous amount of play in the top of the clutch pedal. In addition, the pedal is now about a half-inch higher than it was before the work was done. Is there a way to adjust the clutch release point higher, and adjust the pedal back down where it belongs? This has made it very difficult to drive a vehicle that I have been driving for 13 years. Thank you for your help!
