I recollect that NH itself has a decent list that comes with the tractor or the manual. My dealer delivered the tractor and walked on through all of it, not forcing me to ask a lot of dumb questions. He took his time, told me lots of stories, but also conveyed a ton of practical information about which fluids went where, the kinds of problems people typically have, what the levers, pedals do and how to attach and detach implements. Despite my weeks of reading TBN and having a manual in advance of delivery, the guided tour was incredibly useful. If it isn't offered, ask for it.
Key thing to have when tractor is delivered is a large washcloth with which to wipe the grin off your face....it feels foolish after while.
