1a) Stunning Fist can be declared prior to any attack roll. So, yes, you can combine it with Flurry of Blows. 1b) Scorpion Style is a standard action and cannot be combined with Flurry of Blows. However, you can combine Stunning Fist and Scorpion Style because Scorpion Style is an attack. 2) Wand: There is a lot of confusion regarding the minimum level required for a Craft feat vs the minimum level required for a spell trigger or spell completion item created using that feat. The one has nothing to do with the other. Craft Wand requires caster level 5. Craft Wand is a prerequisite for making a magic wand. A spell trigger or spell completion item (such as a wand) has a minimum caster level equal to that required for the spell. Example: Cure Light Wounds is a minimum of caster level 1 (for a Cleric) while Cure Moderate Wounds is a minimum of caster level 3 (for a cleric). In short, no, the minimum caster level of the spell in a wand is set by the minimum caster level to cast the spell, not the crafter's level or the level it takes to take the crafting feat. 3) Basically, yes. A more correct statement is that all damage you will do will get through the DR. DR is not subtracted from your "damage bonus" but it is subtracted from the total physical damage you do.
