You won't want to encode to MPEG2 and then to WMV. Just give him the DV files directly, and he can encode to WMV from there. If you are willing to spend ~$50, you can also buy a Quicktime export component for WMV, so you could get to WMV directly from iMovie. But even better would be to encode to a standard, like MPEG4.
Quicktime's .mov is a container. It can contain a number of different audio/video codecs, including MPEG4. WMV is a codec, but it is also generally tied to the Windows Media container. It is not MPEG4, though older versions were similar to MPEG4. Divx is an MPEG4 codec, which most people put into an AVI container.
AVI is just a container. It can contain a number of different codecs.
It's supposed to be MPEG1. Just like if you come across an MP4, it's supposed to be MPEG4.
