Skip unecessary registration steps

Im setting up a membership site (with only 1, free level) and I'm wondering how to skip all the unnecessary steps.

Right now when someone goes to my site registration page (http://slate.pixelworklab.com/register/)

They have to select a subscription before registering. I only have one so i dont need this.

Additionally, after entering their information they are taken to another page and have to click "subscribe" again.

How can I clean this up? Thanks!
