Best solution is not to do that. If you upload a road shapefile to OSM, 
it will have no connection to existing roads in the OSM database, which 
spoils routing. Same applies to rivers and coastlines.

There is a tool called shp2osm, which transforms shapefiles to OSM data.
Another possibility is to save the layer as GPX. You have to transform 
polygons to lines before, because GPX does not know polygons (and OSM 
also does not).

You can load that into the josm editor, and download the current data of 
the same view in a seperate layer. Then you have to check your data with 
the existing, add tags as necessary, deleting duplicates, and take 
special care for polygons. In OSM, they are closed ways, or relations of 
type "multipolygon".

Finally upload the changes.
