Real life pilots of airliners almost never use full power thrust at takeoff. To reach your goal of the most realistic preflight and operation of a Boeing 737NG, you need to compute the assumed temperature with its respective de-rated thrust power.
Take in account the weather conditions, your aircraft weight, the runway length to compute your assumed temperature and the respective Vref speeds (V1, Vr and V2).
Is this for 737-700 and 737-600 also?
Yes it is, the product description confirms it :).
