Move the custom feilds above shipping info

Hi there, this is a great plug-in. I’m just wondering if I can move the custom fields above the billing address?

And also, I am wondering if it is possible to have a grouping of 3 custom fields (I don’t mind going into the backend coding to make it happen)

I am trying to gather participant information 1. name/2. phone #/3. email address, for up to 12 people .

thanks!
