I don't understand well about "one hell of a woo". Please let me know the meaning and nuance of it.

A "woo" here refers to "wooing" someone, which means to flirt with someone or make them become attracted, interested, or in love with you. So "one hell of a woo" here means that his act of trying to "woo" her, or make her interested in him romantically, was very good.
