Patience is a virtue but.......

The water change WILL help dilute nitrites. But the trade off is the more you dilute them, the longer your cycle will take to complete.

Yote is right, in that most salts will automatically raise your pH to the correct level. You should only have to add a pH additive after you add salt and let the water mix for at least 24 hours, and then see something wrong with the pH.

As long as you have a bio wheel in use you are going to be mostly developing the bacteria levels in it, not in your live rock or your dead rock you added. Live rock does not compete well with power bio competitors for nutrients, and therefore stay at low levels, and will continue to as long as they must compete for food. Is there some reason you are using a bio wheel in conjunction with live rock? I would suggest weaning your tank off of the bio wheel. Do enough of a water change every day to have enough tank water to rinse your bio wheel off in (say a half gallon). Do not clean it real well, just enough to lower its biological filtering so that your live rock bacteria can grow enough to use the extra nutrients made available to them. Do this until your nitrites go to zero then remove the bio wheel all together.
