Navbar background image woes

[SirTalksalot]

Hi all,

I'm trying to add background images to the navigation menu. The top one is displaying, but the buttons are causing problems, the image repeats itself and there seems to be a one pixel difference where the images starts in places.

As for the bottom half of the navbar, which I've done with a seperate image. That images isn't showing at all.

If someone could show me where I've gone so horribly wrong, I'd be most grateful.
