Need Help using PayPal method

Has anyone use paypal before? I just sold my computer, both the buyer and I agreed to use PayPal for the transaction, My question is, Do I need to ship the computer first and give the tracking number to Paypal in order for me to get the money? But How will I know the money is there because I looked in my bank account the money is not there and I went on PayPal.com and the money is still pending and the buyer just sent the money out of his account today on sunday the 2 of july, Do I wait until it's verified? before I send the computer

Yes if you dont wait for it to be verified, he can cancle payment at anytime. So if you ship and give him tracking numbers, he can withdraw payment and you are -screwed- Wait until the payment clears. Should take no longer then 5 days in my past experience with paypal.
