Hi Colin,

Good to see that you have really caught the OSM-bug.

Not a bad choice.  Why not have a look at
http://wiki.openstreetmap.org/index.php/Proposed_features and revive
Music_venue, or add "stage" or "bandshell"?

Select the node for the traffic signal.  Add highway=traffic_signals to
that node.

I find myself deselecting everything periodically by selecting an empty
space to avoid accidentally changing an island to a road.

vim / gedit will work.
gpsbabel does wonderful things. Try an include polygon that excludes the
Bat Cave.  http://www.gpsbabel.org/htmldoc-development/filter_polygon.html
