The Retainer Clip must be lifted out first before the cartridge can be removed.
It takes either the 1200 or the 1225.
This tool will rock the cartridge back and forth to hopefully loosen it from the walls of the brass body. It then screws in and lets you spin it out. Since your screw is broken, it looks like you may need the pliers.
You can go with the crystal know like you had, or they also make a lever handle trim for it.
