1. You don't connect the cycles surface node to the poser surface node. It is a replacement for it (for superfly renders only). Poser 11 has 3 surface nodes rather than the one poser has had right along. There's alose the physical surface node which is good for PBR shaders. If you look at the cycles surface node, you'll see there is no plug to feed it into something else. Instead, there is a spot to indicate which render engine you want to use it for.

2. The image shows the chrome setup I used. It was something Bagginsbill posted at one time. Where I had the node that said "you chrome shader" I had collapsed it to simplify the view. I don't know what shader you had in mind for your render, but the node you would plug into the surface node is what you would plug into the final mix closure node. When using masks like this, I often collapse the nodes for each of the shaders to make it easier to work with.

you can find the collapse function if you right click on the material pallet
