I don't know how to make the Studio theme look like

I don't know how to make the Studio theme look like the demo. I have it installed at tootsierocket.com/lashenvy
I selected a static page for the home page. I want the slider but after putting in the URL and other information (height, slide duration), it doesn't show up on the page. Instead I have no slider and a stupid form for leaving feedback. I must be missing something really critical about this but I can't find a tutorial anywhere about the very first few things you do when you install a new theme. Thanks in advance for any help.
