set up business theme with nav menu to directory plugin

Hi,

I'm a bit confused. I installed the business theme but it doesn't dispaly as I thought it would..meaning the front page doesn't appear as the one in you demo image and I can't determine where to make those setting changes.

Also i want to use a nav menu link to the directory plugin so that the initial directory shows but am unsure how to achieve that.

Thank you for the help.
