Pro Site Setup

Hi there,
I'm setting up my multisite and would like to know how to accomplish the following:
1. Have a signup wizard to guide users on an easy step by step process like what edublogs or wordpress.com does. Is this build out of the box from prosite or plugins that comes from my subscription? Or is there a add-on or plugin I can purchase to do this easily?

2. I want to offer these plans for website services: 15-day trial, 30-day trial (for re-seller), Package1:$350, Package2:$450, Package3:$550 each per year. Then have them pay for hosting yearly for $150. How can I accomplish this on Pro Site? or what plugin do I need? I want everything to be automated if possible.

Thanks,
Chris
