check this out http://www.cichlid-forum.com/videos/cleaning_sand.php. It gives a good overview of cleaning sand.
As for rocks, big ones shouldn't rest on the sand they should rest on the bottom of the tank or eggcrate. There is no reason why you shouldn't move tsmall rocks around, keeps the fish interested and will make cleaning the sand easier :thumb:
