Keep the collapsible pole or a good 2 piece 6ft on your pack, better yet get a fly rod and learn how to use it.As far as must haves (opinions will vary) for flies that can be used with spinning gear a few wholly buggers will go a long way, some mepps spinners, panther martins, or blue fox work great, also don't pass up the tried and true small bobber and patzkues green label egg. Also matching the hatch so to speak, ie find local grubs, worm etc in logs or under rocks works wonders.. Fishing is simple, keep it that way for the back country, some small worm hooks, split shot, leader and local bait and you will do fine...
