Maybe you could secure the services of a kind lister who has the same kit to 
check it out for you, at least then you could sell it on with confidence.

That's the most universal colour temp, it may look a little warm if you have 
been conditioned to view a native 9300k screen as white though.

Pity, my software (Spyder2Pro V2) allows the cal data to be printed (File > 
Print Information) and the calibration curves can be viewed on screen (Tools > 
Curves).

Only if you are very very lucky. Consistency of calibration between monitors 
relies on many factors, firstly that you input the correct screen chromacities 
but then the final colour calibration has to be visually gauged. The white and 
black points are only relative not absolute (a calibrated measuring tool like a 
Spyder must be used to gauge absolute brightness levels). The gamma adjustment 
tool that is provided only allows gamma to be checked and adjusted at middle 
gray. The application conveniently assumes that the gamma curve remains 
predictable at all other gray levels between the white and black points.

Put a full colour test image with deep blacks and pure whites up on both 
monitors and set them side by side, I'd be surprised if they present similar 
colours and more surprised still if they appeared the same brightness.

I believe that there really is no substitute for actual measurement when 
calibrating screens, whether the gear is good enough to be able to provide good 
results through calibration is another matter.

If you want the achieve the best possible outcome using the Adobe Gamma tool 
and visual calibration then I'd suggest trying the following procedure:
