Stated very well.
the only things that I might add that I tend to do are take the middle of the lane when descending fast (several women have been hit by turning cars while descending hills here - really to be seen well it is best to be out in the middle and its doubly important when you are traveling very fast and cannot stop quickly), at 4 way stops and when turning left (so that a driver does not come up beside me and block my view of traffic and traffic's view of me)
and I never feel obligated to use a bicycle lane if the lane has been designed in a way that makes it dangerous - generally if it is too close to parked cars and presents a door hazard. (sorry Oregon gals, but you can get a ticket for this, but in WA state you don't have to use them)
