That's more or less how I do it as well. But the borders are fuzzy. I 
tend to downgrade when the road goes through a city and there's a 
ringway. Or I downgrade when the primary road ends at two unclassified 
roads for example. And think logically: no need to make a Nxxx road 
with less than ten cars per hour anything more important than an 
unclassified road.

About the roads with refs like N7a, it really depends on the situation. 
They can be quite small or very important links. As is the case for R 
roads, that's also arbitrary.

highway=trunk is for so called "expresswegen": no pedestrians are 
allowed on these roads. They can still have same level crossings with 
other roads though. But I think that it was done correctly in Leuven 
from what I remember of it over there: partly trunk and partly primary.
