The other aspect to maximum driving efficiency is choice-of-route. When I plan a Google maps route I look first at shortest distance, not the estimate of shortest time. Of course, some shortest-distance routes are unworkable for various reasons but often the shortest route gives you the maximum effective range for your trip.
The other choice-of-route factor involves significant climbs. The two things that really drain battery fast are speeds over 70 mph and steep climbs - unfortunately both are very common on the interstate near us. When looking for a maximum-range route I will intentionally avoid unnecessary hills or, alternatively, plan routes that have gentler climbs.
Finally, unless you really like hypermiling all the time don't feel that you have to. It is very good to know hypermiling techniques as they can come in handy in lots of situations where you need maximum range, but it's also fun to put the LEAF in D mode and drive it without worrying about maximizing your miles/kWh.
