Paypal payment method.

Hi,

Address override : If activated, the address specified during the checkout overrides the PayPal member’s stored address. Buyers see the addresses that is passed to PayPal, but they cannot edit them. PayPal does not show addresses if they are invalid or omitted.
No shipping : If activated, PayPal will not prompt buyers for a shipping address.
Allow payment notifications from PayPal : That option should stay on unless you don't want that PayPal confirms automatically the orders on your website so that you can do it manually yourself.
Send details of the order : If activated, all the details of the order will be sent to PayPal. If deactivated, only the full amount of the order will be sent to PayPal.
Enable authorization mode : If activated, the payments won't be processed by PayPal but put "on hold", waiting for you to validate them manually.

If you have a problem with the PayPal plugin here are two documentation pages you should look at:
