ShAf I haven't been following from the beginning so I'm not clear on what you are trying to do, but two/three things things:
Different RGB color spaces will yield different values for the same color. That's why when you convert to profile you can choose to keep the appearance of the colors, but change the number description of it, or vice versa. So what those numbers should be is space dependant. However, for a neutral gray they (RGB) SHOULD all be the same number. Forget what Ned said about RGB being device dependant (sorry Ned), that was pre Photoshop 4, when your monitor profile was used as your system profile (before my time so don't ask). The idea of abstract color spaces, like Adobe RGB, or sRGB, is precisely that they ARE device independent. In the curves or Levels dialog box, where you'd access the gray eyedropper, if you double click the gray eyedropper icon, it will open a dialog box where you can enter the numbers which you want the point you click to be set too. If there are no color crossovers in your gray (where highlights might have a different cast than shadows) the gray eyedropper should work. However if you utilize the eyedropper through curves and look at your individual channel curves after, you'll see only one point on each curve is utilized. The eyedropper will only be neutralizing the point you click on. Color crossovers would require multiple points on a curve, and would probably best be set manually. What I do is select the eyedropper from the MAIN tool pallet. Shift+click up to 4 separate areas to anchor an eyedropper there for readout in the info pallet (shift+drag to slide them around, or drag them off the image to remove). Open a Curves adj. layer. CMD+CLick on one of your eyedropper anchor points and that will attach a point on each curve for that tone. Watch the readout for that point in the info pallet, and adjust each of those curve/points till all your RGB values for that point read the same. Do the same for each anchor point. Then go back and fine tune. It's very hard to get all your points dead on, but if one of your RGB values is off a point or two here or there it's usually pretty unnoticeable in the real world. Hope that helps.
