Space on the right side and space on the bottom (in pages)

I am having some issues with gaps/spacing on this theme. I created a contacts page but it seems to me that the right section is always empty and cannot be filled (even in visual). Also having the same issue with the gap at the bottom of the page which when I reduce, reduces the homepage widgets. Anyone know any solutions on how I can make the right space be filled so its proportioned to the website? and also how to remove the space at the bottom for pages?

heres my website if it helps: www.genioustudios.com
