I found that by doing the following query you can get a list of all schemas or namespaces:
select distinct schemaname from pg_tables where schemaname not in ('information_schema', 'pg_catalog');
In order to select all of the tables within a schema or namespace:
select tablename from pg_tables where schemaname='name_of_schema';
Thanks for the responses.

Is there a list somewhere of the system catalog tables and examples of querying it for administrative reasons?

You can either do it with the INFORMATION_SCHEMA, or the system catalogs. To see how to do it with the system catalogs, then start psql with the -E switch and issue \dn and set search_path='schemaname' and \d
