Ubergadgets

Hey everybody, I have never used CubeCart before but I am really enjoying it so far! I have been able to edit some things through the css file like the color of my hyperlinks. But there are a few things I haven't been able to change. 1 - Below the products on my homepage is a big button with the text '' Koop nu '' ( buy now ) , I want to change the color of that button ( the default colors and when its highlighted ). The same goes for the ''looking glass button '' right of the search bar. Perfect example is on http://ubergadgets.eu/games.html , where all the buttons are blue ( including the one for changing the way of viewing the products ). All those buttons, which are blue, I want to change into two shades of green which I also use for my hyperlinks. 2 - After selecting a category from the topbar ( Computer, games, gadgets, cadeaubonnen ) you enter a page with the links HOME / COMPUTER ( or any of the other categories ) below that topbar. When you hover over those hyperlinks the color changes into the color I want, but the default color is blue, which I want to edit into a different shade of green. Thanks in advance! And I am Dutch, so excuse me for my butchering of the English language
