Thanks, I tweaked her face shape a bit, so it's a little more oval now. Of anyone is interested she's in the Sims Gallery, along with Loki: AoA, under my username Arachne3003.
As for your questions:
1. Dani doesn't appear as much in Fearless Defenders as much as we were led to believe, but she's well written when she does appear.
2. John F Moore's is absolutely worth checking out. It's the closest any writer's really come to capturing the feel of the early New Mutants. Dani's powers do get really screwed up, though. IIRC, there was a lot of editorial interference in the story, as well.
3. Probably her stint as an undercover agent for SHIELD. It runs sporadically through a good chunk of X-Force
