For "Add Event", you need to have evolution installed. In that case indicator-datetime will execute "evolution calendar:///?startdate=DATE" command. Do you have it installed?
"About This Computer" should work fine already… Can you please check if you have $XDG_CURRENT_DESKTOP set to GNOME-Flashback:Unity, and that "unity-control-center info" really works?
