Wildfire, I just see some fine tuning that needs to be done.
Contact Us page doesn't center like the rest of the pages.
Image Optimization
I would export all of your navigation and titles to gif format. Do it from the original format you created them in. This will cut down the size of the files dramatically and likely increase the clarity.
Tip: images that are mostly text, lines, solid colors generally are going to be smaller when saved as .gif. Images that are pictures are generally going to be smaller when saved as jpg.
Example:
Original JPG
~10kb
Export as GIF
~3.6kb
Not sure what graphics software your using but you can probably export those jpg's as something more like 80 quality vs. 99 they are now.
Something is causing your nav to reposition on everypage.
