Whoa there big guy! Most of the questions you' ve just asked have already been answered. You need to slow down some and really focus on 1 or 2 things at most.
First of all you describe a great area that elk are using as we speak. Focus on that, like I mentioned before, most activity is first thing in the morning, midday, and evening. The elk are most likely not bedded there in the daytime.
That being said form a strategy that fits into when elk are using the area. Don' t make anymore out of it than that. If you decide to sit on a wallow, make sure it' s an active one, if it' s a trail, so be it. Of course when setting up, being in bowrange is crucial, so don' t setup farther away than you can shoot comftorably.
If you have further questions, please limit them and you' ll recieve better response. There' s some very good elk hunters on this site. elknut1
