Salam Alikm, About the first point: there are two type of packets ( Data and Control ) packets. control=request+reply messages. Also I am referring you to see the NS-2 manual about Packets in NS-2.
About the second: yes packet_id = $41; 41 column. also try study the output trace file to get more information I advise all the beginner into NS-2 to try simple programs and scenarios.
