Some quick questions on Unarmed and Marksman synergy:

1. Do all Armor Rating boosting Heavy Armor perks in fact boost unarmed Damage when using heavy gauntlets and Fists of Steel Perk?

2. Does the Khajiit Claws Racial Ability stack with Fists of Steel?

3. When punching with a Bow equipped, does that punch get the unarmed damage bonuses of Fists of Steel?

4. Do unarmed attacks get a Sneak Attack critical multiplier? Are the effected by the Backstab perk?

5. Can you Block with a bow, and if yes; is blocking with a bow effected by block perks (as some were in Oblivion)?
