Hi,
I think you have a very nice site, and appropriate for your products. Your graphics are more than adequate. About the colors, I agree that some of them could be improved upon. Please take a look at this helpful website, if you are interested in improving your color scheme:

You might also like to look at the color section of my post today in the Site Design Forum, entitled "Can Your Website Pass the Tests?" I have included many helpful URLs for color problems, including addressing the needs of the color-blind.
As for your text at the bottom of the home page, I suspect you probably added that for search engines, since I did the same thing on mine. I am certain no one will spend the time to read through it, but I hope the search engines will.
For good website design (by the book), you are not supposed to have more than 4 page lengths of vertical scrolling, but then I have broken those rules, too.
I haven't decided exactly what I am going to do with so much text, but I am thinking about inserting some relevant graphics to relieve the eyes, just in case someone wants to read it.
Best of luck with your site. I really do think it is very well done.
