Using the whole page with template?

I downloaded this web template: http://www.freewebsitetemplates.com/preview/gamingtemplate/
I want to use that extra space on the right and left without effecting the main page in the center. Kinda like how some websites put ads along both sides. If someone could help with that, that would be awesome.

what do you want to use it for, I could try to help

pictures and maybe random little blurbs

Did anyone ever get this resolved? Im sort of having the same problem with another template. I am looking to do the extact same thing.

Anyone with any info.?

Thanks.
