membership plugin

Can u tell me is there anyway that i can add the link to sign up for different plans in pricing table (plan comparison table) and plan comparision page.

I also need to add simple registration form on homepage, where user is only asked to add email and password and then in a pop up, he will need to select plan and make payment to complete the process.

How i can i give them 30 day trial for any plan so that they won't be charged for that period but will be charged after that.

Please let me know the answers asap.
