The Eizo tutorials are general because they have to be. In fact I think they are too specific, if anything. They keep recommending a very low and warm white point (around 5000K and 80-100 cd/m²), which will only work under very special and tightly controlled conditions.
But much of this is best done visually, rather than following a recipe. Basically what you want is a white point that gives you a visual match to paper white. Whatever gets you there will work, depending on your working environment.
Then you want a black point/contrast range that also matches the paper. This is equally important and often underrated. As an example, I work mostly for offset print, and I currently have my black point at 0.5 cd/m², which is fairly high. This gives me a contrast ratio as low as 200:1. It looks pretty dull on screen, but it gives me a reasonably reliable preview of the finished result.
The CG246's advertised contrast range of 1000:1 or so I really have little use for...
The CNX edition has ColorNavigator included, right? If not, get it ASAP. It's a brilliant piece of software. I suggest you use it to set up several targets for different scenarios, which you can then switch on the fly just by clicking on them in the list in the ColorNavigator main window. This not only changes the calibration targets, but also switches to the corresponding display profile at system level (which Photoshop/Lightroom uses to display). The only thing you need to remember is to relaunch PS/Lr so that it can pick up the correct profile at startup.
