No.  It means the network address is 127.0.0.0 and the first 8 bits of
the address are for the network and the remaining 24 are for the
individual hosts.  Thus it is 127.0.0.0 - 127.255.255.255.

Yes.

No, no.  You don't want to allow all hosts in 192.0.0.0 -
192.255.255.255 to relay through your server!  (newwer postfix
versions will not start and report an error when technically incorrect
CIDR notation like this is used)  You (Werner) should change that to
192.168.0.0/24.

This is only useful to allow clients on your network to relay through
your server.  It doesn't help if you want to allow roaming users (say
an employee is staying at a hotel on a business trip) to relay through
your server.
