Hi Martijn,
I think it is the right way to import lines first. I normally build the
polygon topology in the second step with the build or clean command in
ARC/INFO. It doesn't make any problems. We had more problems to exchange the
label information, but it is possible too. We use v.reclass in GRASS to
create the labels and import them with the POINTS option in the ARC/INFO
generate command.
Hope this helps ....
Hartmut
