Membership Plugin Used for Registration Page

I am having a heck of a time getting registration going. With the default WordPress settings users don’t get a confirmation email or anything. I want to use the Membership plugin for my registration in the following ways:

User loads page, clicks the register on the login screen, they are taking to the Membership Plugin page so they can register.

Currently when I set up a registration page through the membership plugin, when I click register it takes me to a page showing the three subscriptions I have set up. I don’t want to force users to get subscriptions (which are the top 2 it shows), anyone should be able to join the site for free and be put into a “default” group I have set up (the 3rd option). Thank you for all the help.
