Query about best Shanghai Metro ticket

Is there a ticket which allows me the following travel
Day 1 - one way ticket on the Maglev from Pudong to Longyang Rd, then Line 2 to Peoples Square
Day 2, 3 & 4 - unlimited Metro travel.
Leave the city on Day 4 in the evening via overnight train.

Is it best to buy a separate ticket for Day 1 (Maglev + metro), then a 3 day pass?
