Trying out your TCPDUMP program, how do I go about finding out the Index of an Interface?

Try this:

C:\>tcpdump -D

and then:

C:\>tcpdump -i <interface number> <whatever you want>

Assume, you want to have a look at HTTP traffic on port 80. Apparently, the NdisWanBh intrface is out of interest:

C:\>tcpdump -D
1.\Device\NdisWanBh (WAN Miniport (Network Monitor))
2.\Device\{1F361AA0-9606-4422-836B-8D2465C812B6} /
          (Realtek RTL8169/8110 Family Gigabit Ethernet NIC)

Now let's run tcpdump against the second interface from the list:

C:\>tcpdump -i 2 -vv -x -X -s 1500 port 80
