As far as the crossing wires/ic's...45deg or greater is fine. Not that it would induce noise but typically it's a good idea to not run audio and video signal cables parallel and neither parallel with power cords. Less gear in rig the easier this is to do. I have some audio and video connects running parallel but they are seperated by a couple feet down the back of my av rack. Where I was more cautious was with my surround spkr cables which are run through attic and cross the electrical lines up there. I think 90 deg would be ideal...but not practical.
Tweaks
The latest issue of Absolute Sound has a list of 15 or so tweaks that they say are worth doing. I would like to get some feedback from others about 3 of them.
1. Grounding Caps for unused preamp inputs.
2. Equipment anti-vibration devices such as Vibropods.
3. Aligning interconnects and power cords so that they cross at right angles to each other. (This sounds like a very difficult thing to arrange).
