I bought the Mac wrench the the APE guys recommended.  I also sprayed 
PB Blaster penetrant on the bolts every time I was under the car for 
6 months prior to the brake job.  Even though the wrench they 
recommened is a 12-point, the bolts came off with minimal fuss.  And 
this was on my notorious $450 rustbucket GTV-6 that has required more 
than its share of destructive fastener removal.  $50 made it easily 
the most expensive wrench I've ever bought, but I called Mac tools 
directly with the number supplied on their web page, and they ship 
for free.  As for Bonney, they no longer exist.

As for the adjusters, the inboard ones are different--one turns one 
way, one turns the other.  I have the conventional righty-tighty, 
lefty-loosey one marked with red paint on my car, but I don't 
remember which one it is.  The outboard ones are as you surmised, in 
terms of the 17mm bit being a locknut and the Allen being the adjust, 
but they are both lefty-tighty, if you will.  If the calipers really 
won't back off, then you probably need new ones.  That's how mine 
were when I bought the car.
