That's very close to what I've always done. I have a notification to warn me if I have new failed sign-ups due to payment and keep Paypal responses to catch all sorts of problems. It's just good practice to expect things to fail sometimes. That's also why I have my status page hosted with a different provider and twitter status as a back-up for that.
My favorite Paypal annoyance is that for split payments there's no way to verify that a seller's Paypal account qualifies for split payments (has to be a business account and verified), without trying to send a payment. At least, that's the way it was last it mattered to me.
