I hope to update this post with a vastly simplified approach to using the content presentation feature. Meanwhile, I do want to point out one thing that had me spinning my time for awhile. The URI for the templates TLDs in the sample files  cause a compile error. At first I thought it was because the URI changed from http://www.bea.com/servers/content/ui/jsp/templates to http://www.bea.com/tags/wlpapps/contentui/templates, so I changed it. Then I got run-time errors because some of the methods aren’t in the new library. So I rolled back to the original values and just turned off validation for JSPs. That worked. So I am taking the approach of putting the templates into a shared library and taking the deployment hit rather than the development hit of having validations turned off for the main branch of the project. Later, I should create a build file that merges the projects at build time and drops the share library reference.
