Please help!

I am trying to change the width of my site, so that it doesnt take up the whole page, just about 800pixels (centered). How do i go about doing this? Please help. I have tried the center shop contriution but all it does is mess up my code and i get errors. What am i doing wrong? There must be a way to do it directly.

 

Also, in includes/languages/english.php when i ttry to edit the page title, i get a parse error on line 79 <_< :( what gives? :(
