The gamma setting in Color Settings and the monitor gamma are really two different
things so they are not required to be the same. For the most part the idea is to
pick settings and keep things consistent.
For all my work, I've standardized on Gray Gamma 2.2 and Adobe RGB for color. These
are compatible thus conversions don't cause losses. QTR actually takes the grayscale
numbers directly so profile conversion is not an issue. But all the profiles that I know
of were created with gamma 2.2 working space and that's what I would recommend.
How you calibrate your monitor is independent so if you set it for Mac Gamma 1.8
that's fine.
When you scan film you ought to have the data in 16 bit until at least the major
tonal changes are done and you have it in the Color Setting you want (i.e. gamma 2.2).
