All I can tell you about stance/set-up is that I was taught to always square up to my target, not the lane. So if I'm playing 1st arrow, going down and in I'll be square to the lane, since I'm throwing straight down to 1st arrow. However, if it's dry and I'm standing in front of the ball return targeting 1st arrow I'll be very open in my stance, angled away from the foul line. The swing is constant in all this, only the feet, hips and shoulders change their orientation.
