Directory theme – jobs blue child theme documentation?

Hi,

I am running the Directory theme and using the Jobs Blue child theme (although WP backend says its Jobs Red) and I would like to know how I change the banner highlighted in yellow in attachment. I cant find any documentation for this child theme.

I would like the Right hand side of the banner (quick search section) to have the user login/register boxes, then change the image of the lady, and the text to the Left of her…is this possible?

Thanks in advance for your time!
