Wow, thanks for all of your help everyone.

I usually drive 65-70 miles per hour as the speed limit is 70 here.
(We don't want everyone on the road to think hybrids are gutless!).
I try and use the CC as much as possible.
My commute is probably 80/20 highway/city.

I will increase that tire pressure today.

I do have the AC set to auto, but I have it set quite cool. It is hot right now!

I am trying to watch every move I make while the instantaneous fuel meter is above average so that I can apply that to my driving habits.
