ok well first off welcome to teh fourm!
secondly i manage a "LFS" and can tell you in this hobby MOST fish stores will lie to you but not allways. so shop around if you can.
i sell the same lights you have all day long and its plenty enough to keep almost every soft coral under the sun and most any LPS (large polyped stony) coral. if your not certain about it just place the coral up high and gradualy move it down until you are comfortable with it.
kyroguy is right if you want the shimmer effect you must have a single "point" source of light or a point source type of lighting = metal halides or LEDs but LEDs are probaly not going to do the trick. the reason this is metal halides emit all there energy from a single spot instead of using it through an entire range like a tube. the light is not so much more as in wattage but in intensity. corals dont need watts corals need intensity. so next time someone tells you that this or that amount of light or watts per gallon is enough to keep a certain coral look at them like they are a retard.
MH lighting does no allways need a chiller and for the size aquarium you have and amount of light over it you would be spending more like 300-500 on a chiller not 1000+. keep the room cool (ambient air tempature) and your aquarium should stay cool.
now if the LFS lied to you about the lighting im sure they lied to you about other stuff so if you want to go through an equipment list with me of whats on your aquarium feel free to. also i will tell you if you are paying too much.
