Is it time for my first water change?

[SurfinC]

I have a 90 gallon dt and a 20 to 25 gallon sump I am not running my skimmer yet as I don't have any fish. It has been cycling for about a week and a half now and I tested ammonia nitrite nitrate lastnight and again today. ammonia=0, nitrite=0, nitrate is about 5ppm, and my ph is about 8.0. Should I go ahead and do a water change? and how much water do I need to change? I will be getting more cured/cooked live rock this Friday. Is this ok or should I wait to do the water change?
