Answer 1

From the way you are discribing the functionality it sounds like you want layered navigation. In this case you should make an attribute for caret value and make it dropdown and filterable. Then set the category to anchor.

Below is some information about layered navigation

Answer 2

$collection = Mage::getResourceModel('catalog/product_collection');
$collection->addAttributeToFilter('carat', 'value');

Just edit value to be the value of the attribute you are interested in.

FYI, starting your question with a row of capitals and bold lettering doesn't overly encourage people to help you...
