[Zope] Content Management Design Patterns

Does anyone have a recommendation for "best practices" for implementing complicated Web patterns like Session Tracking, Member Profile management (how to store the back-end data), Multi-cookie storage/retrieval, and "shopping cart" paradigms? I know that Zope (and specifically CMF) provides for these applications, but I'd like a resource on the core concepts & principles. I'm aware that New Riders is publishing another Zope book entitled "Zope: Web Application Development and Content Management", and could this be exactly what I'm looking for? Steve Spicklemire, would you mind whetting our appetites? Thanks in advance, Eron
