How can I move the Login and Register w/ Facebook Buttons?

Hello -

I'd like to move the Facebook Login button and the Register w/ Facebook button, to the bottom of the respective locations. I would also like to provide minimal instructional text to coincide with these buttons. I've looked in several files to try to see if I could move them on my own, but I was not able to find the code where I thought it would be. Can someone give me a quick how-to on this?

Thank you!
