Digital BW, The Print

My monitor is calibrated for Gray Gamma 1.8, so I should be making my 
exposures so that middle gray should read on the monitor as RGB 145. 
Is that correct? Practically all the 21 step grayscale strips are set 
up for Gray Gamma 2.2 and have 128 as middle gray. In addition to the 
monitor set up as GG 1.8 it is set so the color temperature is 5000K 
and I view all my prints under a 5000K temperature light. I don't 
think I am the only one who is doing this, yet Ive seen no questions 
regarding this exposure question. The only reason I ask it now,is 
that I usually need to lighten most of my images before really 
working on them and sometimes the deepest darkest that I would like 
to have some detail in it doesn't have any; as the result of what I 
think may need exposre correction at time of exposure.
