Keyword placement basically just means that you have to use your keywords in the body of the text on the page, not just in the meta tags. "Placement" doesn't mean that they have to be in a particular place on the page, just that they need to be used somewhere in the text. It is most helpful as far as search engine placement goes, however, to have them appear near the beginning of the page.
On your page, I would suggest making your company name graphic a little smaller, since it takes up the entire first screen, and maybe having a short description of your company under it, using plentiful keywords, of course!
