During the stay at hospital, you and baby will wear the hospital's suit. You only need to bring 1 set each for when check-out from hospital. If you believe those traditional thing, bring a hat or handkerchief to cover baby's head when leaving the hospital.

You need to bring more sanitary pads, better bring those for night uses and heavy flow.

Bring thermos for keeping warm water, better drink warm water. Few packs of milo or nestum in case hungry or no appetite to eat food.

For me, nope. No shower or wash up, just the nurse given me a pinch of salt and a "equipment" to "sit" and soak our private part. You may bring facial cotton to wet clean it but i dont like it, i think i used tissue.
