Sometimes it is just a matter of re-synching the window motor. You may be able to toggle the window switch and get the glass all the way up. Then moving the window up and down through it's entire cycle will allow it to re-learn the range of motion.
Unfortunately the broken plastic in the door is probably from the regulator. The broken pulley is probably causing excessive drag in the assembly which the motor reads as a possible obstruction and triggering the anti-trap feature. In that case you will have to replace the regulator assembly.
