Check out reef of the month thread (joe) - he has an awesome sps tank, and has great advice on things like flow, parameters, lighting etc.

why is flow important? sps, like other corals, secrete a mucus membrane. The zooxanthellae do not use CO2 for photosynthesis. rather there is a two step process that uses carbon from other sources, especially alkalinity, so flow helps flush the mucus away so that the carbon exchanges can take place. too much flow or constant flow from one direction on the other hand isn'y good.
As for parameters test often and dose as needed until you are satisfied your parameters are stable.
heed joes advice:
"I state over and over to reefers: “The key to reef success is to keep your hands out of the tank.” Tinker with things to get them running and then let the tank be, it will reward you."
