1) Go to vending machines and buy SP recovery items, don't worry so much about HP restoring items, you'll find them fairly frequently. These vending machines have limited supply but refresh every week. There's a vending machine in the dorm and one in the mall.

2) During shuffle time after battle prioritize new Personas. If you already have that persona then choose money, you'll need it.

3) Explore everywhere around town for Twilight Fragments. You'll need these to open some chests, check every nook and cranny for them.
