NHC doesn't have built in support for NVidia graphics cards (last time I checked) although they may offer it up in the future. NHC will not help you with any difficulties you may have with your NVidia drivers including battery life although as you know you can create custom profiles for your CPU to improve battery life. This has nothing to do with your graphics drivers on this notebook.
84.22 is a more up to date revision than 83.40. While I don't fully understand NVidia's release policies or their driver labeling plans it has been consistent that the higher the number of the revision the more recent it is.
The reason that the 83.40 drivers you linked are of a newer release date than the ones released by Sager is because OEMs will get drivers earlier than we do and will be able to tweak them and release them prior to NVidia's official release. This is actually a pretty admirable thing on Sager's behalf since it shows they are dedicated to making sure their customers get the newest drivers available.
Again, this is speculation but it seems reasonable to me.
You can experiment with different releases of drivers or even with custom tweaked drivers you downloaded from somewhere but if you have problems and contact Sager they will advise you to first install the drivers they recommend for the machine. You can always tweak these drivers to suit your personal tastes and increase performance at whatever tradeoffs you feel is worthwhile.
For more information on tweaking drivers yourself and learning about NVidia's features if you are interested I recommend checking out guru3D's website.
