One thing to consider in the Salo vs Visnovsky debate is Salo's injury history. Only twice in his career has he played more than 70 games (not since 03/04). Visnovsky is typically a better point producer, but Salo will likely have better +/-.
I would give Vokoun a bit of an edge over Kiprusoff as he has a much better team in front of him.
Kane should be better than Seguin and Neal better than Koivu.
I think you would win the trade, but it's pretty even.
