I agree with your approach of starting with the speakers and the amp/speaker interface is very important. I think you are on the right track with Merlin and ARS as from my experience they work well together.
I would re-evaluate the funds set aside for everything else. I know Bobby recommends Cardas with his speakers but I do not think you have to go with Clear. A friend of mine had Merlin's and used Golden Reference which are a bit less expensive. There are lots of other less expensive cable options as well that I think would work nicely too.
In addition, I would hold off on both the power conditioner and room treatments until you had everything set up in your room and listened for some time. I used both extensively for a while and learned I could live without a power conditioner and live with minimal room treatments (basically bass traps in the corners behind the speakers). If you are going to be listening near field, and in your size room that is most likely going to be the case, you may not need room treatments at all.
In any case my point is to shave off some dollars on the accessories and put more money into your source or just get the Bryston combo and set the rest aside until you have had some time to evaluate. It's possible you won't need to spend the full $30k.
