Website help

Hi all I had someone make my a website design, anyways all he supplied me with was a psd with all the graffics that he did on it. Now I have broken most of the site into a few images im still trying to figure out how to make my navigation work.
anyways its I need help making my site look like this.
my banner and my footer images are used as background images in some CSS but I also want the little “wing” things on there as well I took them out because I was affriad it would make the text all wonky. Also I had to use the <center></center> tags on the text to get it in the center of the page how do I fix this? If anyone wants to see my CSS/HTML just say and I’ll post it up.
