padding + color menu + featured content

Hi, A few questions again... www.katrien.co 1. How can I reduce the padding above the social icons and under the menu? 2. How can I reduce the background, the white color around my site? 2. How can I change the color of the menu (if scrolling over and if selected) into #FF0080? And the font? 3. I would like to have only 1 featured content on the homepage (welcome to my website + intro text), is that possible? I can only reduce the number of columns to 3 and I keep 4 featured contents. 4. And last...(for now :-)) how can I make the text broader on the page 'about me'? Thank you so much!!!
