It does end it, but leaves some plot points unresolved. Nothing major though. It's the kind of thing where he could pick up on it in a later book, or just leave it.
Major spoilers:

The only book in the Shadow series that was really worth getting into was Ender's Shadow. And that is so only because Ender was in it. It was, at best, "fun."
I just find Bean very annoying. I tolerated him in Ender's Game, when I didn't know anything about him. But once he hit Battle School in Ender's Shadow I lost it. And he got worse at Command School.
Deadbolt that frakin' door!
Last night I killed a spider.
I think he'll never forgive me.
