Yeah, better said than I did...

In addition, a board where you need analog traces seperated from 
digital and power, traces as short as possible, signals kept away 
from noise sources, power having wider traces, bypass caps directly 
to power/gnd pins, ....

By the way, I have found that parts layout is the most important 
task.  A good layout will route pretty well in most cases.  A bad 
layout will cost you hours and frustration.  That's what I use 
autoroute for - to see if the layout is reasonably optimal.
