Menu:Blog:Font Size layout Help

HI, I am needing some help here is my site (still creating it) http://www.kokophotography.com.au/website/ How do I make the menu button on mobile devices a different colour? How do I remove the line between my name and the menu? How do I make the menu just one line? How do I change the font size of my blog excerpt? I really want to change the layout of my blog layouts, instead of one post per line i would rather 2/3 per line with much less excerpt text (even have the text on the photo/link instead) Can I make the menu static at the top of the screen when off homepage? How do I add an email icon to my social media links in bottome footer menu?
