Janeth, I must admit that your site looks very beautiful and attractive! Visually pleasing.
And I am sure the site can sale.
I would like to add some points I have checked on the fly.
1. I agree with all above about the size of the graphics.
2. What are you doing with your navigation?
You have your main navigation once at the top and also once on the right side of the page.
If you want to also have a navigation on the right, that should be for internal page navigation.
You can re-use the main navigation on your page, but adding it in the footer of you page.
Also, I am missing a site map, or a search function, if you site is larger that 100 pages.
3. You document outlining (semantical structure) is incorrect. You use an <h1> after an </h2>.
4. As Kgun mentioned above, avoid using tables for layout unless the table makes sense when linearized (if it doesn't make sense, then provide an alternative equivalent, which may be a linearized version). Also, if a table is used for layout, do not use any structural markup for the purpose of visual formatting. CSS is recommended for visual formatting. A linearized table is one that makes sense when its cells are read in row order.
5. About opening new windows: Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the user. Avoid using target="_blank" because spawning a new window can be confusing and disorienting to the user. If a new window must be spawned, then it is recommended that it be indicated in the link description, such as by using the text "new window" somewhere in the "title" attribute value or by adding "(new window)" or so to the link description.
Check my very popular tutorial about this issue:

6. As Kgun also mentioned. Why do you use XHTML Transitional and not Strict? If you do that because of the "target=_blank", I can provide you with solutions if you want.
7. Why don't you add your content type/charset in your .htaccess file.
8. Why do you use this <meta name="robots" content="index,follow" />
I looked for your robots.txt
http://www.geeksonsteroids.com/robots.txt and I have been redirected here

Is this kind of
SEO trick? Hm, to be honest I am not impressed. Just sounds dangerous to me.
9. You did not define your document language. You did this: <html xmlns="http://www.w3.org/1999/xhtml">
But it must look like this: <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
To be honest, the best work I have seen from you so far Janeth. Keep up the great work!
