Although the default timberlake template is....well...unattractive to say the least, it certainly can be customized to your little hearts content. As Darrell pointed out you can add some interesting techniques to make the headers stand out a bit more. Although I tend to stray away from the negative margin technique simply because of the fact that I.E doesn't act too kindly with them.

With my latest account for The Office Shop Inc I incorporated a similar yet different technique. Rather then creating a larger header and using the negative margin to make it line up, I simply created a standard header in photoshop and used the "pop off images" partially in the background. The background itself is wide enough to have a 777px blank white spot in the middle with the images on the sides of this. View the background image of the header to see exactly what I'm talking about. Then you center the background with "background-position:top center;".

There is definitely no one right way to incorporate any of these techniques and each of you will find your own personal preference on how to apply each.
