I didn't see any responses to this, but given it is off topic for both groups
that wouldn't surprise me. In the future please direct these questions to the
slony project mailing lists.

More or less. The scripts provided are just examples, but you can modify them
to suite your einvironment rather than write your own.

pg_class with appropriate where clause to get just the desired tables.

Chances are yes, since those scripts were written for the example scenario
provided, and your environment is sure to be different. Again, post to the
slony mailing lists if you need more help.
