Why does my car shift horrible after a new clutch was installed?

What is your question?

I have a 99 Jetta with a 2.0 engine. I recently had a new clutch installed, but now my car doesn't shift correctly. It shifts amazing when the car isn't running (regardless if I press the clutch in). When I shift it into first (while its off) then turn the car on, it lurches forwar a little bit. After the car is on and I stop I cant shift into first at all. Its hard to shift into all the gears and it'll grind if I push too hard. The clutch engages almost immediately after I start to release my foot. While its in gear and its running (when I don't have to shift) it drives good. As I shift into a different gear it feels chunky and it takes at least 5 seconds to shift into a different gear.
