SKoprowski,
Someone who ISFs devices may be able to correct me, but the proper way from what I know (and from what has worked for me) is to first calibrate each component's electrical interface. Component signals (like many other signals) have standards to which they should ahear i.e. a 7.5 IRE window gives x voltage, whereas a 100IRE window gives y voltage.
Once you've calibrated your electrical interfaces, you can calibrate your projector/CRT/whatever to show the calibrated signals properly.
When you get to the point of calibrating your display, you may need to tweak something downstream (like the brightness on your IScan, for instance) to give the projector enough range to calibrate. This should probably be used as a last resort - try to calibrate everything using each device's own tweaks first.
The idea behind this is that while you could leave everything alone except your display and get a good greyscale tracking out of it, it's possible that you're loosing definition due to bad signals (i.e. crushed whites, etc...). If a device has a range which is %125 of the spec'd voltage for a signal, that extra %25 could cause distortion, loss of picture information, etc... On the other hand, it may not cause any problems. Caveat emptor.
You'll probably need at least 1) a disc or other source with a few test patterns and an osciloscope. Cliff Watson has a great page on how to do this with a video card:

Indeed, Cliff has "scoped" a number of different drivers for the ATI series - check out the results on TheaterTek's support forums:
