Skip Vienna, fly with easyjet from Amsterdam to Rome or with ryanair from Eindhoven to Rome, proceed then according to my post 7 and you will be fine.
Expect Rome to be very busy, hot and touristy. I've never been to Vienna but I've heard good things except the cost of the place. I personally love Munich so maybe you could consider that over Vienna? A cold, German beer during the summer in a Munich Bier Garten! Does it get any better?
Barcelona and Amsterdam are very good choices in my opinion. If you're flying between cities then Skyscanner is a great website but if you want to check what trains are available that bahn.com is the one.
Seems like you'll have a good trip. Just don't rush yourself. Maybe drop one of the cities if you think it'll be a hurry.
