Impreza: Disable page site title and add Buttons?

Hey Guys,

I’m actually working on my site:
I want to have an transparnt header. I already got an transparent header but there is a kind of a “sub”-header. I mean the font between the image and the header called “Selbstverteidigung”.

How can I disable that, so that the entier picture is behind the real header? - transparent header
And my second question is. How can I add three buttons and a picture above the background image?

Here is a example how the header, the picture and the buttons should look like:

Thank you!
