The paper and polytype elements are things the team was playing around with but they were never released. You don't need them to make designer work though, so you can ignore the 404s.
What Eric was saying is that if you make a metadata.html file for your component, then add that location to the index.html file in designer<https://github.com/PolymerLabs/designer/blob/master/index.html#L33-L38>, you can make your own components show up in the palette on the left hand side. Right now there's a bug in designer which prevents elements from being dragged onto the canvas so it's effectively broken, but we'll get it fixed this week.
