How about this. Do the article in two parts. In the first part you quote the 20 practices that you feel strongest about, and have permission for. In the second half you comment on the remaining 236 without quoting them, just giving the references to them (e.g. the number of the practice, or the page number). No need to be shy about spelling out the reason for the strange format.

I agree with xdg that it'd be a shame if copyright laws were to effectively silence this kind of review.
