I would rather say you should do the opposite. Light inhibits the
release of melatonin, which is (among other things) why we feel more
alert and happy in bright sunlight and why people often have trouble
falling alseep in lit rooms. Conversely, if you work in the dark you
have a higher chance of becoming sleepy.

Sounds likely. You essentially get a form of jet-lag as your
biological rhythms do not fit with your activity patterns. Try working
in brightly lit areas during the night, and sleep in carefully
darkened rooms during the day. Possibly melatonin supplements could be
used to really fix the schedule.

Not as far as I know, although there are likely some gains to be made
from learning to sleep more efficiently (however that is done :-). The
memory consolidation that appears to go on during sleep is likely
tricky to speed up, but if I find a way I'm sure you will notice. :-)
