Most newbie threads just say "they i got a new car" but don't ask any pertinent questions. You had a line of questions that we could easily answer.
I don't have charging at work either, but with a 65 mile per day commute, I still get 70 mpg lifetime - blows away any Prius. Once the hypermiling bug wears off (it took me two years) you'll still enjoy driving the car like a car and not go too much out of the way for that free charge.
