Question on Druids and how they deal their damage in Wild Shape;

If they have (for example) a MIN II Great Axe equipped when morphing into Wolf form, does the damage they do reflect the Min II's damage or do they do the Wolves damage? The wiki says you will benefit from the treasure effects (so the Acid Burst etc), how about the metalline effect? In this case, will you benefit from Weapon Focus: Bludgeoning or the Axes Keen effect??

Is it always better to go sword and board and take the Shield Mastery feats for the doublestrike %?

Any advice form experience Druid melee-ers would be great (looking to get my PL under my "pelt") :-)
