ObjectManagerItem is not a real class, and seems to have been invented 
for the documentation. You really want SimpleItem, I suspect.

Zope asks each product to provide factories to add themselves. You get 
access to the registered factory methods (like manage_addFolder) with 
manage_addProduct.

mxmEasyProduct makes product bootstrap easier. mxmRelations may help 
your "links." But you might consider using CMF or Plone so that you can 
use Archetypes, which makes development of content types (which is 
really what you have) really dead easy. And it also provides some very 
nice reference machinery.

For finding objects in Zope where the amount or location is non-trivial, 
you will usually use ZCatalog.
