I would play it this way:
Since you are playing everything is DR instead of actual armor, then the DR 4 (from natural) and the DR 3 from the +2 adamantine would give DR 7/-. The fact of being a werewolf grants DR 10/silver. I would list the two side by side. The armor is on the outer layer, so anything hitting the werewolf has to go through the armor, therefore it takes 3 off of the top of everything. The natural armor also takes 4 off of the top of everything, for a combined total of 7. Whatever is left is then DR 10/silver. Ergo if that specific werewolf gets hit with a silver weapon, the first 7 points are eaten and then the remainder damages the werewolf accordingly, since silver bypasses the DR 10/Silver, but nothing bypasses the DR 7/-. An ethereal/incorporeal attack would bypass the armor and natural armor. Anything else is effectively DR 17/-.
