Standard naming conventions are helpful when using ZCatalog.

This is where my ZClass-centric upbringing makes it hard for me to answer...
You may want to look at the PTK and see how PTK objects work (Links,
Documents, etc.) These objects all inherit PortalContent, which acts
similarly to CatalogAware (but adds review features). In a ZClass that is
CatalogAware, the CatalogAware class implements a manage_afterAdd that
indexes the object to begin with. However, with ZClasses this happens before
the object's properties are set. So, you need to then set the properties and
call reindex_object.

However, there seems to be some other problem since your objects are not
even getting added to the catalog.

Glad to help!
