"She would of been a good woman," The Misfit said, "if it had been somebody there to shoot her every minute of her life."

This is an quote from the story "A good man is hard to find" by Flannery O'Connor. Is here "she would of been" a non-standard equivalent of "she would have been"? – And what about the construction "if it had been somebody there…" Is it grammatically OK or is it the expression of O'Connor's play with language?
