First Time in Japan

Hi Daniel!

I have been searching about JR Pass and our itinerary for a few days now and this site have been very helpful! However, i have a few concern and would really appreciate your comments.
Can you help me determine if we would be able to save or JR Pass would cover our 7 day trip?
And can you help add to make the most of our first time trip using the JR PASS? Thank you very much!

We will be spending 3.5days in Tokyo & 3.5 days in Osaka. Maybe half day in Kyoto and 3 days in Osaka
Narita airport - our hotel, Shibuya Station, Shibuya Excel Hotel Tokyu
Shibuya - Shinjuku, Ginza, Asakusa, Harajuku, Tsukuji Market, Roponggi Hills, Odaiba
Tokyo-Osaka- Nankai Namba Station, Swissotel Nankai
Osaka - Universal Studios, Osaka Castle, Umeda, Dotonburi, Namba
Osaka - Kyoto
Kyoto - Kinkaku-ji Golden Temple, Fushima Inari Shrine
Kyoto - Osaka
Osaka - Kansai Airport

Thank you very much for your help! Looking forward to your reply.
