This is basically what I do.

I then use Gthnk (http://gthnk.com) to navigate all my markdown files. I sync with dropbox or seafile, but it's the same basic idea.

Gthnk renders to PDF for printing. In fact, a medium-term goal is full import/export via hardcopy, which requires paper-oriented output.
