More important than the tech package is the fact that you will be driving 25 miles on highway. If fuel economy is a big chunk of why you are buying a hybrid, you should do a cost analysis for the NAH compared to a more F Efficient Prius. Also not sure where you live but as you probably already know, cold weather and the hybirds don't mix well. I don't want to discourage you because there are other beneficial reasons to own a hybrid (the environment, performance, the look etc..), but I do not want you to be dissapointed with such a large investment when your FE expectations are not met or fall short.
