Even Zend sees the need for such a starting point and just ran a contest for people to submit a tutorial just like the one you mentioned. Hopefully something useful will come from it.

We also found this book useful in getting up and running: php|architect's Guide to Programming with Zend Framework

Its a little out of date, what with 1.5's slew of new features, but it was helpful to us in getting our heads around Zends model and controller implementation and some other modules.
