I've owned the Arros and 10Ft. from the speakers is fine. In fact, the Arros can go very, very wide and that will not be an issue.
As for synergy, all three of the amps you are considering would drive the Arros without any problems up to your specified 90db.
Bi-wiring is not necessary and something to experiment with on a try before you buy basis.
If you find the Arros a bit too hot for your tastes, Tara, Cardas and Audioquest each offer some rather mellow cables. I suspect the Audioquest Type 4 would mate well at an affordable price.
You can bi-wire easily by using the spade terminations on one set of cables and bananas on the other. At least at the amp end...the speaker end doesn't matter and can be all spades or bananas or a combination.
I like the Audioquest King Cobra and Kimber PBJ interconnects for their high performance to value reasons. The Cobra might be the better choice for the tube amps because it has a strong bottom end and is shielded whereas the PBJ is not shielded...but is my preferred IC when shielding isn't an issue.
I'm not sure what you mean by power source.
Sounds like a fun system to put together.
