Invoice is sent before payment

I have 2 invoice questions...

1. The invoice is sent before the payment has been done. How can I delay the invoice only to be sent after successful payment?
2. In the "system -> E-mails" there are a lot of e-mails. At which point in the payment process are the following e-mails sent:

- Order creation notification
- Order status notification
- Order notification

It is puzzling me a bit...

Thanks in advance!

Hi,
1. The solution will probably to unpublish the email : Order creation notification
2.
- Order creation notification : at the creation of your order (before the payment)
- Order status notification : each time your order status change
