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.

Thanks,
Komal
