Oh, I can actually help answer those questions.

It's actually a new factory built shortly before the alliance raids, it's just a replica of an old factory that the machines have mindlessly copied.

Because that's what they do: go to worlds and destroy the life there so they can use the planet.
(this is touched in in the raid storyline actually, and spelled out in the journals in the post raid weekly quests)

The first is a place that people can travel to, and the aliens just traveled there.
Nothing is drawing aliens to the source, that's just where we were up until Shadow Bringers so that's where SQEX wrote storylines. If the Omega raids were happening in Shadow Bringers they probably would have taken place on The First instead.
