Disabling Billing Information form in the Plugin: WooCommerce

So I have this plugin called: “WooCommerce” mixed with the theme: “WooStore” on my WordPress site: http://www.Nkapoor124.com

We only want people to be able to pay with PayPal, so we want the other 2 options disabled on the “Checkout” page.

Then, since we only want PayPal, we don’t need any other information from the user, other than their cart information and the total of the order.

We also don’t charge tax and don’t have coupon codes.

So to simplify everything: how do I disable the “Billing Information” form on the “Checkout” page, and also disable: “Direct Bank Transfer” and “Cheque Payment” options for payment?

Thanks in advanced!
