Another way to read the datasheet to get IR uW/cm^2 is to choose either CH1 output (52) or CH0 output (137) and divide by their respective references. So, to get IR value, choose from 52/3474 uW/cm^2 OR 137 / 5338 mW/cm^2.
Using the same approach, white light uW/cm^2 would use the 6024 and 1003 count reference with the CH0 and CH1 counts, respectively.

Well, yes and no. That is an ideal quantity, when the sun is directly overhead (perpendicular to the plane of the detector), on a clear day at a certain time of year. So that has to be considered since it has a huge effect on the measurement obtained.In the terrestrial surface they should arrive on a sunny day about 1000 W/m2
