Digital Coaxial Cable 75 ohms choices
The Theta coax is very good, especially for the price, around $190. Be carefull of the connections, they can easily break loose. You'll find it very smooth and natural. I heard George Cardis had a hand in designing this cable. 
Canare digiflex cbls- Which end is which
I agree with the previous comment. I have talked to canare reps though & they say their cables are non-directional, hence no arrows. hifigy 
CD recorder Marantz or Pioneer
I agree with ranstl. Seek out an HHB pro unit. It's based on a Pioneer unit but has all the pro connections & defeatable scms. It doesn't copy hdcd. I have an HHB 880 (the previous model) and it's fantastic.

Ken, given the size of your room, I don't think you can go wrong with Dunlavy SC-IVA's, even the IV's are a bargain used and woth seeking out. With the IVA's you won't need your sub unless you have an lfe out on your pre-amp. I've owned the SC-IV'... 
What is the best digital interconnect
The MIT mentioned above is very good, a bit lean in the bottom end but, otherwise it's great. Theta's coaxial is a suprising value as well, very balanced top to bottom. If you really want one of the best, the Synergistic Designers Reference would ... 
Best speaker for 6 grand max.
The Dunlavy SC-IVa is hard to beat if you have the space, but don't rule out a set of SC-IV's. The money you save could go into a great set of cables. 
Best amp for Dunlavy V
The VT-200 is a great match, especially with Synergistic Designers Ref spkr cable. I tried Krell FPB's, the bass was great but, everything else was too in the face. I agree with haipo's comments
