Question: energy....? when going down a hill, is potential energy converted to kinetic energy or is that the other way around? and how does conservation of energy relate to roller coasters?

Answer: Rolling down hill is turning potential energy into kinetic energy as you said. Conservation of energy relates to a roller coaster ride. going down a hill gains enough kinetic energy to be able to convert the kinetic energy into the potential energy gained by climbing the next hill. The reason the hills can not be the same height is that friction converts some of the energy into heat.
