i think i have the XML format worked out, but i have a few questions:

1. i thought the general idea was that the XML defined the identity and layout of the webparts on the page. Therefore what's the difference between requiredWebParts and preferredWebParts?

2. I assume 'modules' determines what modules are enabled and 'defaultModule' is that start page?

3. In the default workbook template, Dave added some extra UI at the top of the page. Instead of the default title, the workbook says something like '166: Title', where 166 is the workbook number. Can we do stuff like that? I assume I can create a webpart with my HTML, then add it with frame=none; however, can/how would I go about replacing the normal page title? see here for example workbook:
