How do I style the Directory Signup pages?

I'm trying to style the Directory Signup pages.

1. I am only selling listings for $100 a year. So, how can I hide the radial button and have it auto select? This just slows down the signup process because you don't even think to click it and then are given notice that it's required.

2. How could I put the terms of service in an iFrame? Right now the first step is to scroll way down the page

3. I'm only using Paypal. Can I get rid of Step 2 all together?

4. How can I add some text to Step 3?
