Basically you open your Paypal account and input all your personal contact information. Since at this point you have no money in that account you will need to link it to either your bank account for instant transfer or assign a credit card. Then when you send money it will prompt you for the payment method you want to use.
It's pretty straight forward. Just take some time to go through the setup process. Make sure if you do add a credit card, that your billing address for the card matches exactly with the address you provided for your Paypal account.
And yes, he will get the money before the product ships. That is standard business practice. Make sure you are comfortable with this person as a seller.
