Ran into the thing myself, installing the "Functional Content" stuff does nothing, found that I had to scroll down further on page to where it says
Additional solution: Install the Resource Central library content
Then I choose "English" to start the download. Is about 1.7GB I believe, and follow the instructions and this gives you ALL the goodies for Encore!

this gives you ALL the goodies for Encore!
This is true for the Encore "library." The "functional content" install adds some content to Premiere, and also installs the Encore "Styles" and "Templates" (for flash export) directories.
So I believe the best option is to install the functional content, which is an installer than puts things where they belong; then use the add the Encore library to the library directory.
I just confirmed that there is no significant content in the functional content library install that is not in the full library install.
