There is no good reason why Q would spend all that time trying to woo Janeway, when all he wants is a to have a child.
Sure he can do it way easier in other ways, but I imagine that he liked the challenge of trying to seduce Janeway. Q seems to have a thing for Starfleet captains. Why else would he have himself wearing a Captain's uniform all the time?
Also no, I doubt Q would have ever magicked the Voyager crew himself. He would have wanted them to do it themselves
I always believed the map Q gave them at the end of Q2 was his way of pointing Voyager in the direction of the Borg transwarp hub in Endgame, to take care of a problem for him (Q themselves are not to provoke them).
