Just few other thing. Misplacement of you component, bad PCB design may and will ruine your life when they're not correctly done. Supply line must be bigger than the signal one and, IMHO, routed at first with the capacitor stuff. Once it's done and correctly done, you add your signal line one the top/bottom (and middles if you use multilayer PCB).

NEVER trust any autorouter CAD if your design is critical... Even with the best one and all the according restriction/direction defined, it may screw up your life. Well that what i'd discover after ages of PCB design.

I'm sure you don't want to do some PCB modification later because it was bad designed. For a single project it's ok, for a hundred/thousand/million unit.... ARRRRGH!
