Do I need a rail pass for Kansai?

My husband and I will be traveling to Japan in Sept.
This is an idea of our itinerary and the rates I got from Hyperdia.com per person:
Are the rates correct and would it be more economical to get a rail pass, if so, what kind?
Sept. 20-Take train from Kansai Airport to Kyoto 1,768.74 yen (1-way)
Sept. 23-Take train from Kyoto to Nara 1,372.94 yen (round-trip)
Sept. 25-Take train from Kyoto to Matsumoto 9,749.52 yen (1-way),
then bus to Kamikochi, after 2 days, take bus to Takayama
Sept. 29-Take train from Takayama to Kanazawa 3,957.09 yen (1-way)
Oct. 2 -Take train from Kanazawa to Osaka 7,392.90 yen (1-way)
Oct. 3 -Take train from Osaka to Kansai Airport ?

Please let me know what would work best for us?

Aloha,
Jeannie
