1. We use OSM maps for navigation, and so management are quite able to
see the value that could arise from our giving this data to OSM,
because it would make the maps better. But there is a bit of a gap
between lots-of-GPS-traces and lots-of-well-tagged-roads! What can I
do to bridge this gap? (I mean, trace over the GPS trace, I know, but
that's going to leave a lot of 'highway=road' tags; is that okay?)
That's fine -- it's much better than nothing
2. What form of permission do I need to get from management, and where
does it get saved? Is there a pro forma letter somewhere? What licence
do we release the data under?
You'd be releasing the data under CC-BY-SA and ODbL. If you are acting
on behalf of the copyright owner, then you don't need to add any further
documentation -- simply uploading the data is enough to show you agree
to the licences.
3. Is a single daily trace suitable? I mean, all vehicles' traces put
together in one file and uploaded (under, I guess, a separate account
-- but still owned by me)? Or is there some automatic way of doing this?
A separate account for the traces may well be a good idea. As for
aggregating the traces, I don't see any benefit to OSM of doing that,
especially if it involves you doing more work. If it's the effort of
uploading multiple traces that worries you, there's an Alpha-quality
Java utility that I'm happy to help you to use:

But really: is this worthwhile? Will my company benefit? Will OSM
benefit?
Yes. More source data is always good, especially if it's based on real
movements.
