Your question should be "what MIB modules does it implement?". An agent 
does not load
any MIBs. The atm example implements, among others, the ATM-MIB.

Most of the MIBs are implemented by the AGENT++ framework. They are used by
many examples. Take a look at the agent.cpp file and you will find it 
out easily.

It implements the MIB, yes.

Provide a different port at the command line. You can use any value 
between 1 and 65535,
but some ports are already in use (see your etc/services file) and for 
ports <1024 you will need
root privileges.

That depends on your manager. For the agent, you can use SNMP or configure
it within the agent. (See the agent.cpp of the ATM example for instance)

See above.

Yes, of course.

Yes.
