Show Header Image all pages/Change location of header media text

Good Afternoon, I would like to make the header image show on all pages, but I can't seem to find a way to do so. Also, I would like to change the location of the header media text to be on the right side of the image, rather than centered. Preferably I would like to decrease the size of the text as well. Finally, I would like to change some of the fonts, specifically the font of the main top right link. Can you please help me on how to do so? Cheers.
