First I would scrap the table and use a css based layout. You should also get used to working in split view so that you can see when styles are being added in EW which is what all the style1, style2, style3, etc are. I usually create the styles first and then apply them BUT if I do inadvertently create one, I change the name to something that lets me know what it is for. You basically have a top header div, a div that is floated left for your left side navigation, a content div and the footer div. All this is within a container div. It will give you the same look as the table you are using. A div is just a division or section of your document. This explains the <div> tag in more detail http://www.w3schools.com/tags/tag_div.asp
My favorite starting place is http://www.inknoise.com/experimental/layoutomatic.php However if you want a headstart, you can use any of these
http://www.genealogy-web-creations.com/css-layouts/index.htm which are based on the above layout creator. This one probably comes closest to what you are trying to do. http://www.genealogy-web-creations.com/css-layouts/site1.html You can view the source and see basically what I did. Instead of the more complicated menu you are using, you can use one that is a css based menu layout that would look something like this http://www.the-gearys.com/david/index.htm
Your doctype has some extra stuff in it that is usually caused by copying and pasting from another MS program into Expression Web. See http://www.genealogy-web-creations.com/xmlns-validation-error.html for a complete explanation.
I would change the blue to another color as it does not quite go with the tans and browns.
CSS is not hard, just think of it as having your content in your html coding and your presentation or styling in your style sheet. Tina has a free e-bokk on setting up Expression Web to get you off on the right foot and another one on creating dwt's or dynamic web templates in Expression Web

A lot at one time. Read it over and if you don't understand come back and ask questions.
