10 days in Tokyo and Kyoto - JRpass + Suica & N'EX?

Hello,
I am travelling to Japan in April and will be there for 12 days. I am planing to spend most of my time between Tokyo and Kyoto. I have a rough itinerary below. My question is: Given I am visiting for 12 days (i.e. between 7 and 14 days) would it be best to get both a 7 day JRpass and a Suica+N'EX pass to cover travel from the airport to Tokyo, travel around Tokyo itself and travel to the south west? Or is there perhaps another option I am unaware of?

Tues 3rd - Arrive in Tokyo (Narita Airport).
Wed 4th - Travel to Kyoto
Thurs 5th - Kyoto
Fri 6th - Kyoto
Sat 7th - Kyoto
Sun 8th - Osaka
Mon 9th - Hiroshima
Tues 10th - Tokyo
Wed 11th - Tokyo
Thurs 12th - Tokyo
Fri 13th - Tokyo
Sat 14th - Depart Tokyo (Narita Airport).

Many thanks for your time! ^_^
