Thanks for your business and kind words! I'm really glad you like them, and am also glad you had a good experience at Pacificon with us.
Now, on to the questions:
Spears do not have the 2-hands Weapon Trait, so you can use them in Close combat with a Shield or Buckler. Pikes, Great Swords, Great Cleavers, and Great Bludgeons, as well as Halberds, all have the 2-hands Trait. If you are walking around out of Close combat and have a Shield, then you get to use it toward your Armor Rating. If you are in Close combat and want to use your 2-hands weapon, then you can't use the shield. However, each Turn you can choose to use different weapons if your model is so equipped. For instance, my Pikeman with a Pike & Sword can use the Pike in Close combat one Turn, then because its Unweidly, he must go to his hanger (sword) for subsequent Turns if he's Engaged in the same Close combat.
And you are correct on the Unarmed question. CBT/2 and Low Impact, which grants your opponent a +1 to his Armor Rating.
I'm working at getting some resources together to produce some tutorial videos for the website. I'll be sure to make many loud and farreaching announcements once those go up, which should really help with all the nuances found in the rules.
And you are correct Stew, you can post any BoB related questions here and we'll get them answered.
