I'd use the source tag on the highest level features, i.e. if a node
belongs to a way or relation then I'd only put the source tag there
and not on the node, same for ways and relations that are members of
other relations. This should be enough for another mapper who comes
along and wonders if his data is of better accuracy to be able to tell

The normal thing to do is load the new file into JOSM, load existing
data from OSM onto the same layer or a separate layer, then remove
duplicates, merge tags etc etc. (for example your imported data for a
building may have way better geometry, but fewer attributes such as
name, height, access, so copy the tags onto the imported shape and
remove the original building).
Then merge the two layers and upload. If the imported file is too big
to load into JOSM, split it with osmosis.
