Here you go..
1) Remove subscribe rss: Go to Canvas / theme options / layout / Primary navigation. In Primary Navigation, untick ‘Show the Subscribe to RSS link in right navigation’.
2) Footer: Go to Canvas / theme options / Footer customisation. In Footer customisation tick ‘enable custom footer left’ and tick ‘enable custom footer right’. This will get rid of the custom branding, and you can also put your own words in here if you wish.
