I know this is a newbie question, but I cannot for the life of me figure out where I am supposed to browse to to access my webDAV directory…any help?
From the documentation of the Enable DAV logins feature:
Enable DAV logins?
When this feature is selected, mail and FTP users within this virtual server will be able to use a DAV client (such as Windows Network Places) to access the /dav URL page and manage web page files. Only users for which DAV access has been enabled will be able to login though.
Means, the URL is http://yourdomain.com/dav
I just tested it, with the Total Commander WebDAV plugin, and it works indeed. 
hmm, odd, when i browse to www.zautools.info/dav i get a 404 not found
Is the DAV feature enabled for that domain? Under Services -> Configure Website, do you see “Location /dav” under Per-directory options?
Anything useful in the Apache error and access logs?
yes, its there:
Directory /var/www/zautools.info/public_html Directory
Directory /var/www/zautools.info/cgi-bin Directory
Location /dav Location
Okay, so, what about the Apache logs?

If I create the directory /var/www/dav, http://www.zautools.info/dav just indexes the directory, no login required
this has been resolved. The problem was in a customized server template.
