Problems with new theme.

Hello,

a few days ago I downloaded them from http://www.smashingmagazine.com/2010/11/24/sight-free-wordpress-3-0-1-ready-theme-for-magazines-and-blogs/ and I have a few problems.
When I add this theme to xampp/htdocs/wordpress/wp-contnet/theme and open this them in WordPress 3.04 on my local host (for right now I use only local host, but in a future I will put this web on a normal host) I see web without graphic (only logo, background and some facebook icon).
And I woluld like to change some graphic but I don’t now where, I now where change logo and I did this. I don’t now wher cancel this white line on the backgrund, if a have to be honest I woluld like to add some photo on the background place.
Where can I add topic and photo for slide show (with size graphic, photo should I add in slide show) ?
I have to translate LATEST ENTRIES for Polish language (I am from Poland) and I don’t now where I can do this to.
I would like to add some text between logo and search, and where can I add name of general topic like web, art, connect, photography.
I use wordpress in Polish language and some things are in english, for me it doesn’t change anything but it is good for work with this theme.
Sorry for this questions, but I am beginer. I started use WordPress a few days ago, and I need some help for sure.
