Please tell me all wiget and plugin needed to make my site like the demo of this theme

HI there, I’m new at here so please tell me step by step to make my blog like theme demo.

What plugins and widget I need to use when I use this theme ?

And in my site, the picture is not changed automatically like demo. And there is a gray blog ( i guess that must be a missing widget ) on the right bar.

Please see pic for more details

Thank you so much. I like this theme very much , its so fantastic !!
