Get in the best shape ever...not that your fat now
If you are bow hunting, I would dedicate some time to the meat care thread and familiarize yourself with the area. Make a pack out plan that would utilize some creeks along the way to cool the meat.
If you are rifle hunting, make sure you can reach out their quite a ways. I would think 500yds could be very realistic in that country. A friend of mine took a great bull at about 650 across a canyon. After many hrs, that was what he could get. He had a turret(sp) setup and made a great shot.
Good luck. I have this unit on my radar for deer at some point.
