I generally agree with your 'shape of the pop'n distribution curve' comments, but the life expectancy thing is off. It's a common problem and comes from the high infant mortality before modernity - that is the main thing throwing it off.
Life expectancy has not gone up all that much (yet) if you measure at age 30 or so.
