1: Upgrade to 7.4.18 (or whatever the latest is) as soon as you can. Use
pg_dump with the -s switch to get just the schema and objects but no data
out. pg_dump --help will give you a list of all the options that command
has. To put your new schema into another database, just redirect that file
to psql:

pg_dump -s -h olddbserver olddbname > schemafile.sql
psql -h newserver newdbname < svhemafile.sql

2: pg_dump is the best way to go. pg_dumpall can dump everything, including
user accounts from one server. Then feed the output to psql or pg_restore.

3: pg_dump is export, psql or pg_restore are import
