Re: Understanding Zen Cart Architecture
I didn't find any further documentation per say, but I have spent a great deal of time in the ZEND development platform, looking at code, and forming a mental map of how everything fits together.
I was going to try to port code from OSC, but I found an easier approach to be just inspect the modules available for download, and look at their structure, and get a feel for the tables in ZC and their relationships. I did have some success with the mod for gift registry, wish list but I did a lot of custom php code and changed it's functionality quite a bit :-S
good luck with your search...

Also, I highly recommend Super Globals Plus:

Not only as a debug/troubleshoot tool, but as a learning tool for stuff not documented (yet) in the Developers API and the Zen Cart Code Documentation.
HTH,

Re: Understanding Zen Cart Architecture
Sorry for the self promotion here, but I think this article I wrote may help you a bit with ZenCart module development. Payment modules may need some extra code in specific areas, but this article about extending ZenCart without touching core files can shed some light on how ZC is light-years ahead of osC.
...and welcome to ZenCart!
