You can download the planet dump from OSM, and there are scripts to convert it in to postgis, though I know of none for oracle.
GeoServer does not support GPX or OSM. I think someone is writing a GPX datastore, and writing one for OSM wouldn't be hard. But the problem with those will be there's no spatial index, so they won't serve very fast. I'd recommend converting to a database to serve it. You also could convert to shapefile, they have scripts to do that I believe, though that holds up less well for transactions.
As for reprojection, once you get the data in to GeoServer then it can reproject it in to whatever projection you want.
The one thing I'm not clear on is how you'd contribute back to OSM? If you just use their editing interface then it works, but then it'd be awhile till your data got the update. I would like to work with them to figure out how we could set up GeoServer's as nodes on to the main OSM database, to let contributions there go back in. Soon we should be able to handle logins, and perhaps could have a version that hooks straight up to their user database and does authentication the same way, and then could do batch imports to their main db.
As for GeoCollaboration stuff, yeah, it's goal is to enable similar things in GeoServer, not so much direct integration, though it should make direct integration easier, and we would be very psyched if OSM or at least part of the community made use of GeoServer. They've shown no interest in the past, but we lacked authors and versions and all, which are now emerging.
We still need to do a lot of UI work on it, but you can see our first sketches at http://geo.openplans.org/tschaub/wfsv/feature-editor.html#
It's better when you set most of the preferences to true. And you can try viewing the history and do diffs there, and then click on numbers to do rollbacks.

Hi,
I have never tried it myself, but you can download all OSM data in
one bundle. Have a look at
http://wiki.openstreetmap.org/index.php/Planet.osm
<http://wiki.openstreetmap.org/index.php/Planet.osm>
If you are in UK there seems to be also a smaller excerp available. From the same page you can find more advice as well. Tell if you
will have success.

*Aihe:* [Geoserver-users] Open Street Map and Geoserver
Hi all,
I wonder if someone has any experience of using Open Street
Map? I'd like to contribute to and then use Open Street Map
data in my applications but I have come up against several
problems and I wonder if anyone has any suggestions.
1. Open Street Map is recorded in lat/long (4326) but we use
British National Grid Projection (27700) so if I'm to be able to
display OSM data in OpenLayers I need to be able to convert the
bounding box for a WMS request to lat/long before requesting
it. Even then if my understanding of projections is correct it
will come out slightly skewed? I could use Oracle to do this
since it has a transform function which transforms co-ordinates
from one projection to another but this has been shown to have a
slight offset (with Google earth at least) so may not be good
enough. Does Geoserver have any external functions which can be
used without having to get into the java?
2. Ideally it would be nice to be able to periodically copy the
data from Open Street Map, reproject the whole lot and then
serve it from our own server using Geoserver but Open Street Map
only allows downloads of small sets of data at a time and they
are in .GPX or .OSM and I can't seem to find any way to convert
them. Does Geoserver have any plans to support either of these
formats?
I have read the GeoCollaboration page on the wiki but this seems
to be less about direct integration with Open Street Map and
more about enabling that sort of project to be run using
Geoserver. Is that right?
I realise I should probably post this to the Open Street Map
mailing list but I thought I'd get your thoughts on it first?
