hi, this is the 1st time I using paypal to do the payment, I have some question

Case,
We booked a hotel for our taiwan trip on coming may, but they request a deposit from us via paypal. So, now I open an account and link my public bank debit card just now. So what should i do?

1) I linked my public bank debit card "got VISA mark" with my paypal account already, is'it need waiting something from public bank? like code or wat, or straight can use?

2) others than RHB bank no need to top up also can use? even the paypal account balance is zero? after make the payment will be deduct from debit card?

3) the deposit request is based on taiwan dollar, so how it deduct from my debit card? based on bank currency rate to deduct?

please help...thanks
