Certainly looks like some PDF modules are available ... if only in-development.
As an alternative, just fyi, we've done similar display & PDF export of formatted data within a CMS (not Drupal ... yet), where we've split the problem, moving high volume PDF generation to a Tomcat-hosted document processing app.
We query & format data for online display from within the CMS, taking advantage of query-building and display tools (like CCK?) then export data in any available, well-defined XML format. Next, external XSLT transform of the data to XSL-FO format, and finally conversion/generation of PDF using Apache FOP (http://xmlgraphics.apache.org/fop/#intro) running on a Tomcat servlet container (If you already have Solr running on Tomcat, it's convenient ...).
We've done this for transformation of flexible online medical record presentation to strictly-formatted PDF for print and electronic delivery. The fine-grained control of the XML -> XSL-FO transformation, using Xalan, Xerces, etc. results in 'professional quality' output, and offloading to heavier-iron ensures we've never bogged down the CMS.
All depends on what your particular needs are.
