PayPal order number

1.
Let say the customer buy a product with PayPal. The merchant gets email from PayPal with confirmation of payment. But there is no number of hikashop order the customer paid.
Do you know how to solve this problem?

2.
Is it possible that the order status automatically changes from created to "payed" for example when customer pay with PayPal or Moneybookers?

1.If you turn off the option "send order details" in the options of the paypal plugin, you should get the order number in the notification.

2. If you activated the option "Allow payment payment notifications from PayPal" in the plugin's options, you should get the order confirmed automatically.
If you don't, you should check on that:
