Well, the first question that comes to mind is if you know what the spending and ATM limits are on the card. If you don't, you can find this information at the PayPal site under Profile > PayPal Debit Card.
I don't know if PayPal has a toll-free number any more, but here's a number I jotted down back in 2000 for verified premier members: (888) 221-1161. The PayPal card has a phone number on the back that, although not a toll-free number, I have heard from a couple of other sellers will get you in touch with reps who will know what they're talking about.
Good luck,
Ernie.
