Hey Moose,
Outside of the ins and outs of shooting your elk, consider the following. November in Alberta could be pretty COLD. Aside from carrying all that WOOL you were advised to take make sure you have a warm place to recuperate at night time. You didn't say whether you staying with an outfitter, ranch house, or your own tent. But if it is the latter make sure you have some arrangement for HEAT. Problem is, heat and tents have had a nasty history of killing people with carbon monoxide so here is the fix! Go into your local hardware store and by a battery powered CO detector - it will only cost $35-40 and its comforting to know when you go to sleep at night that you will actually wake up in the morning.

More power to what DARTanian said about knowing your rifle regardless what you are shooting. The bench rest lets you know its on target, but try shooting some of the more unusual angles and positions so you don't have to practice it when the elk is in your sights. Steep uphill, steep downhill, left hand, sitting, off hand (steep up and down)and off of the side of a tree. Good luck on your hunt.
