Overall, the site looks great! Here are some observations:
1. The header image looks crowded, both vertically and horizontally.
2. On the rotating blurbs about community, I would decrease the size of the titles so that all the words fit on one line.
3. The titles on your clickable images seem too small, and the fog effect is not so attractive as another form of rollover selection.
4. For the Quick Links, I would suggest adding some words: "Quick Links to Purchasing Options" or something along those lines.
5. The Main Navigation area in the far-right sidebar is impractical. No one is going to go there to navigate. It all needs to be in your menu bar or in an obvious place on the top left. I would probably put the search box at the top right corner, the navigation area on the top left, and two columns of clickable photos running down the center.
6. Putting your testimonials on a different page with a link from the menu bar would give you more room to do some of the things suggested.
The site looks fine as it is, but these are my observations. Good luck with your revisions!
