a fluid layout normally consists of em's or %'s! That way it can and will adjust to the users screen resolution. Also it wont work well if you use position:absolute or relative with it. Thats because of top, left, right, bottom will all be different. Use paddings and margins and floats also. here is a good site with examples.
Your sidebar can stay at the width its currently set at. Use pixels for its width. Your content area will need to have a repeating image going in the x direction so it expands with the users screen resolution.
You could always keep your header graphic centered or start it on the left and have some type of repeating background. A shiny gradient would look okay.

Let me this straight. I'm going with coding it as a fluid layout. A fluid layout uses percentages. It grows and shrinks. Well my first step is slicing the design in Photoshop any specifics I need to know when slicing it to make it optimal for fluid layout coding? And regrading the Content area I do not understand fully what you said Aerospace Eng
what he means is that your content area needs to have a reapeating image so that it can expand with content or the size of the users screen. you would take a small slice of your content image, lets say a height of 5px and the width of how large you want it. It all depends on how it looks.
Then you would repeat the content
Code:
#content {
background-image:url(contentIMG.gif);
background-repeat:repeat;
}/*just an example*/
check out slicing web based images on google and you might get a few examples of how to do this. Let us know if you have anymore questions.
Yes. Take a look at the link to the layout I posted. You won't necessarily need to use percentages you could use a left margin on the content and float the sidebar to the left. The content will expand to fit the screen.

I just tried. I'm not able to grasp this. Maybe if someone could code just a column I can get a better hang of it. Don't worry I wont bug you to code more. This is just to help me.
