With no disrespect to the OP or any others in this thread ...
The hardest thing for me to get my head around when I first got into Studiopress was image rich pages, and/or categories with posts and content must be created FIRST before one can even view the "home" page as it appears in the demo theme areas.
Once I understood this, I found all the tutorials or "documentation" very easily because I knew exactly what I was looking for
, be it dynamic content gallery config., featured page/post widget use ... it's all here and very well laid out IMO.
I also realized my basic understanding of WP in general was very weak,(just look at some of my earlier posts) however, even when it wasn't a theme related issue, but a basic WP function I failed to grasp, the support here always went above and beyond!
Just create some posts/pages, add some images, you can always delete them later after your home page is set up and you can see what you have created. You will get a feeling of empowerment when it all comes together.
My $79 investment in my first theme wouldn't have gotten me very far "hourly" wise talking to the caliber of professional designers and coders here on this forum whom are waiting to help you, and this in itself has been well worth the price of admission, and I thank each and every one of them for sharing their time and amazing talents with me and making Studiopress what it is.
Not to mention other members whom have taken their time to lend a hand or share ideas.
I have found you will not be belittled or made fun of here, so just ask and you will receive the help you need.
