From 9.0 on, you could use ALTER DEFAULT PRIVILEGES to
set default permissions for objects you create.
So yes, if you are using 8.4, you'll have to set the permissions
for every object you create.

With pg_hba.conf you can restrict access to the database to
certain IP ranges, if that's what you are asking.

It does not make much difference, except that the owner can
use ALTER/DROP DATABASE. As long as a user has CREATE privilege
on a database, he or she can create schemata in it.
