Do both stations (Tokyo & Ginza) have elevators or escalators up and down between the street level, ticketing level, and train platform?
Your best choice is to get off at Ginza to transfer to Marunouchi Line. The bus stop at Ginza is very close to Ginza Station, and the Marunouchi line station is located on level B2, while other subways are on deeper levels.

You can access Marunouchi line Ginza station platform taking two elevators from the ground level.

Follow on the map the red line indicating the barrier-free route. You can take the first elevator from somewhere in front of the Nishi Ginza Department Store.
I don't recommend Tokyo Staion to transfer at in your case.
