7 or 14 day JR pass for 2 weeks

I will be backpacking throughout Japan this July for two weeks and wanted to know if I should get the 7 day or 14 day pass based on itinerary.

• Fly to Narita
• Narita -> Tokyo (7/24-7/29)
• Tokyo -> Kyoto (7/29-7/31) day trip to Nara
• Kyoto -> Osaka (7/31-8/03) possibly take a day trip to Kobe)
• Osaka -> Takayama (8/03-8/04)
• Takayama -> Tokyo (8/04-8/07) possibly take a day trip to Nikko or Hakone

Would be cheaper for me to get a 7 day JR rail pass and either a Suica or PASMO card while in Tokyo?

Thank you for any suggesstions
