Hi,
1. Check these settings of your PayPal payment method:
Customer address : If you want, you have the possibility to include the billing or shipping address of your customers to the paypal payment engine. That will avoid them the hassle of reentering it on paypal if they don't already have a paypal account. That option is turned on by default.
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: Based on that option PayPal will display the shipping address form or not:
2 Required -> prompt for shipping address, and require one
1 Yes -> do not prompt for shipping address
0 No -> prompt for shipping address, but do not require one

2. I'm not sure you can change that. If you can, then it might be an option in your PayPal merchant account. I would recommend to contact PayPal's merchant support about this. They will be able to tell you.
