Hi,
the print and export features are available as a TablePress Extension that needs to be installed and activated like a regular plugin: http://tablepress.org/extensions/datatables-tabletools/
For the question about the combo box, I don't really have a direct solution. I suggest to create one page per table, insert the Shortcode there, and then use some custom JS to switch the pages, based on what was selected.
Regards,
Tobias
