Read a few reviews and as long as you keep your soft corals up high in the tank you should be able to maintain them. Do some more research before dropping cash those corals.

Do hard corals then not need as much light as soft corals? (I'm not getting any soon, but I would eventually like to fill up my tank with hard and soft corals if the lighting permits me to do so. If the lights can't handle this task I will probably take it back to the store.)
And also, if I go to the fish store to get live rock, do I have to cure it at all?

I moved the half dead Xenia up on top of the middle rock so it is at the highest point in the aquarium which is about two or three inches higher than it was.

That is good on the xenias. They are not as light needy as many many other corals. In regards to SPS LPS (Hard Corals) are very light needy. Some more so than others. On a scale they are much harder to maintain than softies.
Does that light give a par value or light temp? Also the reviews say no on hard corals.
I would recommend posting a new thread just for this light. I will also look at the specs on the light itself. Was it a 36"?

Talking about how many watts/gallon is pretty useless in reef keeping. A watt is a unit of energy consumed by the bulb, which actually has little to do with the usability of the emitted light. Much more important is the number of lumens, the wavelength and the PAR value of the light. These three factors interact with each other, and depending on the type of lighting (fluorescent, incandescent, LED, metal halide, for example) their interaction and effects vary. This article gives a good explanation of the meanings of these terms, and helps you to decide what type of lighting will work for your system. The old rule of thumb, 2-5 watts/gallon, is sort of true for freshwater planted tanks, but at that light level you will be able to watch your corals wither and die.
