Answer 1

I can tell you, that for an in-app purchases PayPal is most definitely a no go, but you will find this out by yourself :)

Apple will only accept payment for such activities through in app purchases, no other methods of payment are allowed.

There is a workaround for these type of purchases (especially PayPal); do them not within your app but from mobile Safari. That will work and is (for now) an accepted method used by more applications.
