Header problems

I’ve used a WP theme before but now have trouble with simple tasks when using the Activation theme and have been struggling for a week! The problems are with the header and menu area. 1) The menu under the header cuts off a lot of the image. 2) Also the page title appears in the image area. If I add a “side” menu, the image area increases because the main menu moves down and the page title disappears from the header image. But the side menu is in the image and placed just beside the main menu. I don’t need two menus there! I do like the main menu under the header but I don’t want the image cut off. And I don’t want the page title in the image. 3) Lastly I don’t see how to make sure the header is duplicated on every page.Thanks!
