Hello,
1) We have 13 static blocks for the default version http://prntscr.com/vcjk1c
Do you want to get static blocks from other demo versions? What blocks do you need in addition? Could you, please, provide us with the screenshots of the blocks you want to get?
2) Are you talking about the Downloads area on 8theme.com? It includes the bundled plugins if you can’t install them via WP Dashboard > XStore >plugin installer due to server permissions and some additional archives like additional Revolution slider templates or Import files for the manual import of the demos pages, sliders. If you don’t have problems with the plugin installation via WP Dashboard you don’t need the mentioned archives.
Regards
