JR Kansai Area

My itinerary are as follow;

Day 1 (SUnday) Itami airport to OSAKA (Shin-Osaka Station)
Day 2 (Monday) within OSAKA
Day 3 (Tuesday) Shin-Osaka Station - KYOTO
Day 4 (Wednesday) within KYOTO
Day 5 (Thursday) within KYOTO
Day 6 (Friday) KYOTO - NARA (day trip), NARA-KYOTO
Day 7 (Saturday) - KYOTO - Itami Airport

There will be 3 of us. Based on the itinerary above, what is best way and most economical way to get around? I understand that you have only maximum 4 days pass for JR Kansai area.
What do you think will work for us?
- For day 1, should I just settle for the individual tickets from Itami Airport to Osaka? - For day 2 & 3; within Osaka only, evening depart for Kyoto; Is it worth to get a 2 days pass? - For day 4 to day 7 ; Kyoto, Nara and trip from Kyoto to Itami Airport; a 4 day pass?

Awaiting your suggestion.

Regards

Roger
