runway lights medium intensity, regardles if its VFR or IFR. only if the cieling is pretty low do i like them high. in the cokpit i like the lights set pretty low. just enough to see everything well. never used the overheads though. for chart lighting i've got a green and yellow surefire.
landing light off during the day. will turn it on when cleared for TO
and cleared for landing. once i'm handed off or in the pattern it's off too.
all flight plans opened in the air. i'll close VFR ones in the air too once i'm within about 15 nm of the airport. IFR plans i close on the ground.
with uncontrolled fields it depends. there are a few pretty heavily used ones here near NYC. a few also have the same CTAF (kinda annoying.) usually, about 10 nm out.
