Cristiano has imported the data freed in Merano in November, which followed a similar conversion path. Might be some reusable tools there?
The main trick, as I understood it, was to convert the Shapefile data model, which is list based, into the network model of OSM. That means finding intersecting streets, and have the Way reference a common Node. Also, convert directly into the OSM format, and upload via JOSM -- this allows a manual check on the data and preserves all the tags, etc.
Now that we've had 3 or 4 imports from Shapefiles, we should at least start to collect knowledge in the wiki, if not build some generic tools to help this process.

Subject: How to import shapefile into OSM
Hello,
as
a
result
of
the
1st
Italian
Mapping
Party
we
have
some
geodata
freed
by
the
Municipality
of
Arezzo.
The
data
is
in
ESRI
shapefile
format,
any
suggestion
to
convert
it
into
OSM?
We
need
to
open
it
in
JOSM
before
upload.
I
already
managed
to
reproject
into
WGS84
and
eventually
convert
into
GPX,
but
in
this
way
I
lost
the
tags,
e.g.
highway
names.
It
seems
to
me
that
the
TIGER
import
scripts
are
too
TIGER-centric.
Happy
Mapping!
