Retrieving my Responsive Theme Homepage

Hi I’m stuck again, the homepage components have moved to different locations, how can them back to default? The text box and call to action are now in the center of the page, with the feature box below it, and the 3 widget boxes are underneath each other instead of in a line across the page – It is so difficult to get things done, although i am following the tutorials by the book?

Also, it appears fairly simple to add an embedded video link to the feature box but I can only get the code to display, not the video?

And finally, how can I edit the text, so I don’t have to use the very large default font – Is there a plugin?

I am assuming the guys in the tutorials are using the paid version or WP Responsive theme that has all the functionality that I seem to be missing, built in?

Regards

Pete
