Hi it is very easy to get products of particular category in magento.
Check the below peace of code , with this you can get the products of your desored category


$products =
              Mage::getModel('catalog/category')->load('put your category id here')
            ->getProductCollection()
            ->addAttributeToSelect('*') ;

you can also add the filters in the above collection to get your desired products
like if you want to get only enabled products in the particular category like

$products = Mage::getModel('catalog/category')->load($catid)
            ->getProductCollection()
            ->addAttributeToSelect('*')
            ->addAttributeToFilter('status', 1) ;


with this only products enabled will be show in list. You can add as many as filters you want.

Hope it will help somebody.
