Help with 3

Couple things I can't understand with rpg 3

1. I've killed death twice and he hasn't dropped anything? I've had a fleet with me but pelted him with damage. Yet no drops? What's the deal with that?

2. How do I get the large lance? I've conquered their homeworld, plus after killing so many of their ships, one never seems to drop?

3. I'm also assuming when I've captured the annoying Taln home world then the Un-whoever will become friendly and let me buy their things?

Thanks
