Regarding CSS for a quick and dirty fix, what you need to do is use:
The above wont let the layout move around where using display: none; will. @aldous was on the right track though.
Otherwise like @dave mentions that one of the template files needs to delete or comment out the part that is requesting the info to be displayed.
You can't tell exactly which template without actually looking in the themes folder.
in the meantime, I see that the theme is from themezilla, they also have a forum which your question may already be answered.
