How is the society structured? What is important to the warriors in Beowulf? What qualities did they feel a good king should possess? What do they consider "courageous"?
You have a number of specific questions here for this short-answer forum but I can make a a general comment. I believe the warrior code is called comitatus. It is a bond /warrior code between the lord and his thanes in which the lord provides for his thanes in return for loyalty and protection. The code is based on loyalty/fidelity, generosity, bravery and fate. So, if we examine what Beowulf and the soldiers do (except for the ones that wimp out against the dragon) we can see this code in practice.
