I don't know what kind of quality you need, but this video shows how to get rid of a background around a person, yet preserve their hair.
Edit: Oops, on re-reading your post I see you have Photoshop CS2. The above won't be applicable. Sorry.
This looks great, but I don't think my version Cs2 has "Quick Selection Tool" on the toolbar. If you have any other suggestions I would appreciate it. Thanks.
