Thanks!
Definitely sounds like I should try to get a handle on the OM approach.

First of all, I you have 1500 objects, you may not want to print their name.
Each time you log a message it ads to the execution time. On a small bunch of
object it doesn't matter that much, but on longer lists it may affect execution
time significantly. If you really want a log message to show progress you may
print such message only once every 10 or 100 objects. Only when the script is
giving you troubles you will force it to print every object.
Now Kim is 100% right, using the object model instead of the command model will
make your scripts enormously faster. In fact, do not pretend you know scripting
until you use the object model (or at least know how to use it!) ;-)
So lets's look at the various of your script... (see [Bernard] below)

[Bernard] Remove this logmessage, as explained above.

[Bernard] There is a way to replace the set key commands. First, apply
an fcurve to the parameters you wish to keyframe. The AddFCurve() method
will return a FCurve object. Now use that object to add keyframes, with
the AddKey() method.
The AddKey() entry in the docs have a good example of how to do these
two things.

[Bernard] The same applies. Instead of setting keys onto the
transformation of the object, you should add fcurves and use addkey().
