I would make sure you always carry food, water, fire, game bags, extra clothes, rain gear , a good knife, a frame pack , binocs ,,rope wherever you go. Try not to carry too much weight in your daily hunts but enough to butcher an animal immediately and carry the first load back with you.
Learning to call is handy but not necessary for a good hunt. Some of the best elk hunters out there never blow a call. Depending on where you hunt calls can really hurt you, especially if you aren't very good.
Raking trees, splashing in the mud, and breaking branches are often very effective calls to mix in.
Best advice is to enjoy the whole experience and keep on the move until you find ultra fresh sign. You will SMELL when you find a good spot.
Good luck and if you can stretch the hunt out if possible. Even in the best country 5 days and a stick bow will go quick!
