If you build a Sturdy structure and pay attention to key areas like Z-axis then you won't go wrong or notice if COG is off a little, but you will notice if the little details are missed.
That's the paradox I guess! I keep reading all the theory but as I haven't done this sort of a project before it's hard to tell what's essential and what's not. And as you rightly point out, doing the details/assembly properly will matter quite a bit for the end result (as it would for any project really), maybe even more than getting all the theory right ;)
