If I call NETCMD$ on the same port from multiple locations in my program, will this cause problems? Does one NETCMD$ call block others from accessing the port and force them to wait until the first one receives a response or times out?

The PLC execution is a single threaded so at any one time, only one Custom function may be executed and therefore the NETCMD$ will have to be completed before the custom function can return. Hence there is no possibility of two NETCMD$ being executed simultaneously.
