I can help as we have a similar homepage:
We're on Jive Cloud. When you use a news page, you use tiles (not widgets). The top tiles with the banner style image is called a Hero tile. You have to create an image and insert the image. Here's a handy link for best image sizes: Optimal Image Sizes
The tiles on the right hand side are a mix of HTML and Helpful Links tile. The tile in Jamie's homepage above in the wider column is a Banner tile. The rest of the wide column will make up your news streams, top & trending content etc.
Hope this helps
