1)archery is great option if you dont want to charge then attack with out doing much else or be the guy in robes. Bow damage is bad at low level till you get a cm bow then you are doing the same damage as you had a longsword. Also with special arrows(depending on what books avalible) you can add in a cool factor.

2)nice to run around the enemy shooting arrows with skirmish. But could be handicaped if you get in a tight spot.
