1. Armour (light=leather, medium=chain mail, heavy=plated mail) provides protection but needs to be trained as well. The reason for this is that when you first put your armour on, you aren't used to it yet and don't know how to deflect attacks with it best. Especially in the case of heavier (medium or heavy) armor, it makes it harder to move (although every armour type has this disadvantage).
2. The only thing you *need* to do is target and then select one of the stances (bloody, aggressive, normal...). And be careful not to be killed (running away is a wise decision sometimes)

. And to take advantage of your sword skills, you just need to have a sword (or two swords) equipped.
3. Glyphs are a gift from the god Talad, so I can imagine they may appear on such places. Never found one myself though, someone must have got there ahead of me
