Treeclimber, this late in the season, I would stick to what you know best. If your most comfortable with a bow then that's what I would do. Obviously it will be hard to find a successful tree stand spot without any scouting/field time. IMO, spot and stalk may be your best bet at this stage.
You mentioned bugling in an elk, IMO, this is hunting at it's pinnacle! Again, you're a little late to try and master reed type calls. I would suggest some sort of push or blow cow call. This will limit mistakes but still get the bulls talking!
I also wouldn't worry about the crowds this season, use them to your advantage and follow them! Remember, they're there for a reason! When you have more time next season you can get some more separation.
