Yes that's basicly it. The layer tag says which way is above the
other. You can add layer=* to either way (or both) but a rule of thumb
is to add it to the shortest way (usually the bridge).
http://wiki.openstreetmap.org/wiki/Bridge has some more info.

The bridge and the underlying waterway/rail/etc shouldn't share a
node, which can be annoying when maping townlands that follow both the
bridge and the waterway. In those case, you should use an extra way
just for the townland boundary. For example
