Regarding the two placemarks issue, I've gotten a simpler reproduction case. I
believe the main problem is inconsistent balloonVisibility behavior. i.e. try 
pasting
this into GE5 several times (deleting the placemark in between attempts):

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" 
xmlns:gx="http://www.google.com/kml/ext/2.2">
 <Placemark>
   <name>placemark1</name>
   <description>(balloonVisibility = 1)</description>
   <gx:balloonVisibility>1</gx:balloonVisibility>
   <Point>
     <coordinates>2.294785,48.858093,0</coordinates>
   </Point>
 </Placemark>
</kml>

Notice that the first time, the balloon may pop up, but after that, it fails to 
show.
