page dropdown menu in center

What I'm trying to do seems like it should be simple, but I am missing something.

I want to list child pages in the center section (not sidebar). For example, I'd like to list this page:

http://northcoastimports.com/beta/cc...-bird-and-leaf

in this one:

http://northcoastimports.com/beta/cc...uckoo-clocks-3

and this one:

http://northcoastimports.com/beta/cc

But I want it to show up in the center, instead of using the list pages widget on the sidebar.

Can you give me a step-by-step? I tried to figure out how to add a widget area in the center, and use the FlexiPages widget, but got lost several times.
