I've never read any Ghost Rider comics, so this is all new to me. Apparently there were at least two versions. One rode a motorcycle, this one drives a car.
According to a video on youtube the new Director is a character from the comics, he is a future Captain America. Coulson for reasons not yet disclosed allowed himself to be replaced as director.
The book mentioned in episode 2 is apparently encountered by Doctor Strange in the comics.
