Your work sounds really interesting - get it published so I can read it! :)

In my experience in discussing the contents of interviews, I've found discussing theory and inserting bits of the interview text and then my commentary (and repeat till you've said all you can) tends to work best for me... I'm sure others have success with other methods - and I have encountered full renderings of interviews in books that were great to read and provided much more context than just seeing bits of the interviews inserted along the way would have. so, um, I guess I have no real answer for you...

Also, I don't know if this is relevant to you/your writing but recently I've been reading complaints about anthropological writing that it turns very interesting subjects into horribly bland reading - and I've definately encountered such stuff (even the most interesting anthropological accounts tend to lose out to memoirs and novels when I chose a book to read) - and I'm definately guilty of this too. So, unless your professors are dead set against it, I highly recommend going beyond thick description to incorporating anecdotes and interview text as much as possible.
