Try the tried and true 1/3 1/3 1/3 room division and the equilateral triangle shape as a starting point. Measure your room into thirds using the longest length. In theory, your speakers would be 4’ 4” from the front wall and your listening position would be 8’8” from the front wall. Start with the front of your speakers 3’ from the the front wall. Then set them 5’ apart, tweeter to tweeter. Then measure maybe 4.5’-5’ from the front of your speakers and make the triangle. That’s where your ears should be. Start with your speakers aimed at your shoulders. Right speaker aimed at your right shoulder, left at left shoulder. Everything is variable, but these are generally good starting points.
My speakers have the tweeters are mounted too high and the speakers have to be angled down a bunch! Otherwise the sound is really dull! It’s really important that the tweeters are at the same height as your ears!
Oh and I don’t know about getting a Bear skin rug, but a carpet and pad is a great place to start with room acoustics.
All the best.
