Customizing The Homepage and Background

Hi there. I am developing my webiste www.fadeville.co.uk using the audioman theme on wordpress. I would like to remove the home page that appears right above my footer, the whole block written "Recent Post" - "Hello world". Under the tab "Releases" - I would like to remove the grey background color, I would love it my background on post to be transparent that as I scroll, my posts appear as if they are floating. Please assist. Thank You!
