I notice that there is a new Knowledge Base article, "How to create a Shared Folder" <http://kb.parallels.com/entry/37/496/>. The instructions are a little vague--in particular the vocabulary doesn't always match what you see on your screen--but otherwise it seems helpful.
It doesn't answer your question about how to find your folder in OS X, although you can see the full OS X path you originally chose for the folder by hovering your cursor over the path in the Shared Folders window in Configuration Editor. Or, you can put your cursor over the vertical divider between Path and Mode. When your cursor changes to a cross-hair, you can drag the Path header-bar to the right until it's wide enough to show the full path underneath it.
