Good question. My best experience with stereo in a smallish room was to put aside visual design and practical considerations for awhile and listen near-field. Make an equilateral triangle with your chair and the two toed-in speakers—my assumption would be five to six feet on each side of the triangle. Just listen that way for a while, make some minor adjustments and don’t worry about the practical side. Your Benchmark components and Totem speakers are very good.
It never hurts to bring in a professional to help you at any point, but he or she will likely try much of what has been described in responses to your question.
Enjoy!
