Eclipses don't last that long. It wouldn't really be all that difficult over a couple of thousand years for humans to adopt a 32 hour awake/16 hour asleep cycle, maybe with a nap in the middle. Of course most of the time the night will be fairly well lit what with the giant moon and the close stellar companion. In fact the moon will be reflecting so much light that there would probably be noticeably less difference between day and night temperatures.

As for the very thin atmosphere, it would be...difficult to colonise it without actively modifying humans to fit using something like magic biotech. Just about impossible. It doesn't help that 80% hydrosphere means their sea level is comparitively high. On the other hand if somewhere in there they have a super-Grand Canyon, something that goes really really deep at the bottom they might get up to Thin Atmosphere there. But I can't imagine how to keep it from filling up with water.
