Good luck! It’s a big unit and there are elk in lots of places. I don’t have much specific advice for you because I don’t bow hunt. But when I was there last October and it was real hot/dry, elk were tight to water, so do with that what you will. And I’ll be there this November with a tag, so leave one or two for me.
You don’t need to backpack to hunt that unit. You can’t get more than a couple miles from a road and most of it isn’t crazy steep. You’d probably just end up sleeping where you should be hunting.
