Answer:
Climbing = Gerund
To skydive = Infinitive
Won´t let her = Infinitive
Waking hours = Participle
Are spent = Past Participle

To skydive is the infinitive with preposition to linked to the verb wants and is the object. What does she want? To skydive. I´m not sure but I think it functions as an adverb, because it adds something to the verb want.
Won´t let her is an (accusitive) infinitive functioning as an adverb.
Waking hours is a participle that functions as an adjective to the noun hours.
Are spent is the past participle of to be.
