Adding image to background of front page center body only
 

Hi, I want to do two things:
1 Place image to background of front page center body only
2) Snug the image up toward the nav bar without padding

I have tried to put the image in the background of the page using "Add HTML/CSS Inserts" using the code:
/* background image for home page */
body.home td#middle(background-image: url(/wp-content/themes/atahualpa351/images/illustration3x1150.jpg);
background-position: center left;
background-repeat: norepeat;
}
But it is not working and maybe is not the best way to approach this.
I have been able to add a background color but not able to add an image.
Any suggestions or directions?

Below is the site I am working on and I have attached what I want to do as a jpg:
