Hi SkinnerCS,
Provided I understood you correctly, the easiest way would probably be to do the following to the .navigation section:
.navigation {
width: 100%;
position: absolute;
top: 50%;
margin-top: -33px;
}
This would center the navigation vertically above the header image. You would then have to increase the z-index of the logo to put it above the navigation. Give it a try, let me know if it works out.
