IIRC, I chose the format output by Ettercap and used by L0phtCrack for
challenge/response pairs. CAIN's files should contain the same data, but
fields may be flipped around and I think they use TABs to delimit.

I don't follow the section question. L0phtCrack isn't needed for any of
this. You just need to extract the challenge/response hashes from
somewhere (e.g. Ettercap, modified Samba log, packet capture of
SMB/LEAP/PPTP authentication, etc.), drop them in a file and run John.
