Concerning the footer you should go to Theme Options and select footer color and light color scheme for the font. How to create footer you can watch the Legenda video tutorial, as the process is identical.
If you want to change font you can do this for all elements in Theme Options > Typography. Unfortunately we don’t have separate settings for the menu.
If you import other pages and font isn’t changed there, then font styles may be written while creating a page. In this case you need open the page for editing and check the element where the style isn’t changed.
Regarding the logo please try to change folders permissions where your image is located to 777.
