Can you help with your membership plugin please?

I've looked through the guide for this plugin, but I don't see mention of the specific issues that I am having.

How do I set up recurring billing? I'm trying to drip my content out over time, but I want the paid subscription to automatically renew until cancelled but I don't see an option for this.

I need to edit the text when you go to pay for the subscription. For example, when you go to http://www.controlmyadhd.com/register-2/
and clip the sign up button, it says:
"you will pay $47 for 1 month, and then $47 for one month, and then...." on and on for each access level. I don't see any direct way of editing this.

And finally, I did a test signup on an alternate email, and the receipt that comes with the signup states my personal email as the reply email! How do I change this to the business email?

Thank you so much for your help! I'm currently super stuck...
