The lightsaber in the foot was because they hadn't thought about the four arms yet.
But Grevious was crippled around that time as well. They should have explained it in the movie so it made sense, but near the end of Clone Wars his rib cage was partially crushed by a jedi. I can't remember which one, but Grevious was coughing because of that or that's my theory.
I like the Ventress parts from there mostly.
