Well with all the questions I've asked, I owed it to the list to at least
try this in spite of what the doc said.

So I created an empty nav event proc, and immediately my Nav dialogs have
title bars and are moveable and sizeable under both OS 9 and OS X, and
furthermore they are now app modal under OS 9 in addition to OS X.

Everything behaved correctly except for updates behind the window. I fixed
this by simply calling my existing (non-nav) dialog filter proc from my nav
event proc like so:

pascal void NavEventProc (NavEventCallbackMessage callBackSelector,
NavCBRecPtr callBackParms, void *callBackUD)
{
if (callBackSelector == kNavCBEvent)
{
DialogRef dlg = GetDialogFromWindow (callBackParms->window);
short itemHit;
MyDialogFilter (dlg, callBackParms->eventData.eventDataParms.event,
&itemHit);
}
}

And of course, while I said I tried this "in spite of what the doc said" if
the truth be told the doc told me it was "highly recommended" to do this.

Thanks to everyone for their help over these last several days on all the
navigation issues that came up for me.

Ian please note you need not go looking for any code snippets.
