Transport dilemma

Hello,

(Apologies I just tried to post but my PC crashed and can't see if it has posted).

Myself 30 and my partner 30 will be travelling to Tokyo on the 19th April 2019 and have the below itinerary planned out. We just need a little help with figuring out the best way / Quickest / Cheapest way to get from A > B.

As it is golden week during the last week of our stay is it also better to prebook all travel in advance?

Any advice on the above would be greatly appreciated and also if you have any must-dos for the below destinations ;)
