One Pager Website Help

Is there any documentation already on building a one pager site? I would like a couple parts to work like this example http://www.google.com/nexus/7/index.html

Where there is an image area in the background and I can put text on top. For the content areas I am thinking I could use the 1/2 1/2 boxes and that should be no problem. Just stuck on how to add those image sections in between the content sections.

Another question would be: is there a way to set the menu up when clicked it would go to a specific section on the page?

And, that arrow on the bottom right of the example site http://www.google.com/nexus/7/index.html when you scroll down the arrow points down and if you click it you will be taken to the next section and then when you get to the bottom it changes to the up arrow. Is that a feature in Enfold?
