MarketPress with no login required

OK, I went back down to 2.8.4 because I had some problems. My event is on Saturday, so at this point, no plugin or theme updates.

Here is my question.

We are delivering eProducts.

We do not want them to be required to put in their address, but it's OK if they do.

We need name and email.

1) With PP Express Checkout, will MP pass any data collected there to PP if they use a credit card instead of PP account?

2) What settings in products and plugin settings do I need for digital products, 1 quantity only, email and name only required?
