Answer 1

If your user purchases an item and then loads your app onto another device and purchases the same item, it will not charge the user for the purchase. The answers to your questions are in the docs here:

http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StoreKitGuide/Introduction/Introduction.html

In particular, on the chapter on making a purchase the docs say:

If the user attempts to purchase a nonconsumable item they have already purchased, your application receives a regular transaction for that item, not a restore transaction. However, the user is not charged again for that product. Your application should treat these transactions identically to those of the original transaction.
