That 220 watt fixture above isn't going to work because it's not going to cover the tank properly. I would go with 2 of the 120's also. It's enough for whatever you want to keep.
I have montipora on the sand bed of my tank doing well. I had to lower them because they were bleaching under the 120 watt fixtures.
Look for the ones with 30 blue and 25 white. they look nicer than the 30 white and 25 blue, unless you get the dimmable version.
*edit* These are not "good". These will do the job. Good fixtures are starting at about 400 each. You'd need 2.
