Answer 1

As stated in the official documentetion: https://developer.android.com/google/play/billing/billing_reference.html

The response intent to the purchase includes several fields, one of them being:

INAPP_PURCHASE_DATA A String in JSON format that contains details about the purchase order. See table 4 for a description of the JSON fields.

Inside that JSON, you have several fields, also explained in that page, the one you are looking for is:

purchaseToken A token that uniquely identifies a purchase for a given item and user pair.

All these is quite easy to follow from the official sample application, which I recommend you to download and try out, also to check the code.
