For interconnects, you can't go wrong with Columbia. I have some of these myself and feel its the best value in the AQ line. Its easily as good as other cables I have that cost a lot more. Another important issue is that they sound good with anything. Generally speaking, AQ copper cables are known for their high compatibility with most gear. The King Cobra is another IC you may want to look at. Its basically the same cable as the Columbia without the DBS. I think the DBS sounds better but I have never done a side by side comparison to tell exactly how much better it is.
For speaker cables, if they still have some CV-8's left in stock, I would buy them. If not Rocket 44 or 88 should be more than enough for your system.
I'm not a big fan of Best Buy but they do have a decent return policy. I doubt you'll use it, but its good to know that you wont be stuck with them if you are not happy. I's recommend AQ even if you could choose other brands.
