Not sure how much the Audioquest is, but I have used Signal Cable Ultra shotguns in a very expensive system and they performed extremely well, so it may be one to look at as well.
I second the stands, for monitors this is your biggest tweak. Make sure you get the tweeter at or near ear level with the height of the stands, and make sure the stands have some decent spikes. I have used VTI stands in the past and they are pretty decent and very inexpensive, Target (not the retailer) makes some decent metal stands as well for low $$.
Your next challenge will be the room, get the speakers placed where they have decent bass and the stage doesn't collapse against the wall. This will take some time and trial and error.
