I just answered this question for someone else:

You don't really "import" files into OneNote. In this respect you can
think of OneNote as a kind of word processor that just re-opens all the
previously opened files every time you start it. All you have to do is
open a OneNote 2003 file using OneNote 2007 and it will ask you if you
want to convert the file format.

Move the files where you would want them to be using Windows Explorer. If
this is within a currently opened notebook then the sections will simply
show up in OneNote. There will be a bar that indicates that they are read
only unless you convert them and gives you an opportunity to convert
them. Once they are converted you can't convert them back so make a
backup first.
