First off: if you're able to surf the internet, you're able to make preliminary inquiries as to airfare yourself.

As to budget: with the current position of the dollar, you'd have some €115 per day on a 45-day trip. Cheapest accom in the cities you name will be around €25-€30 pppn. If you can find a cheap flight, this looks about sufficient. But with the information you provided it's difficult to say for sure.

As to cost of EUrail: look here

Eurail tutorial:

http://www.ricksteves.com/rail/

The tutorial is decent, but it has one big flaw: I compares only normal fare train prices with the price of the Eurail pass. It does not compare special offers, bus tickets or plane tickets nor gives it any hint that these are alternative options.

Budget: You should plan on having at least 50 EUR per day and person, but 65 EUR per day and person would be better. That is just enough for hostel beds and food from the supermarket though, so if you want hotels and dining out plan on 120 EUR per day and above.

Airfare: around 600-1000 USD roundtrip including taxes from a major airport in the USA (New York, LA, Miami, Chicago, ...) to one of the hubs in Europe (London, Frankfurt, Paris, Rome).

Well - to add to the learned advice already put up, you'd be well off to get the cheapest flight to a major European hub airport (ie - Frankfurt, Manchester, Amsterdam or London Gatwick), then checkout some budget airlines within Europe. It has some of the world's cheapest prices to get you around - very quickly too.
Have a look at EasyJet, Jet2, Ryanair and Wizzair. You will see some incredibly cheap fares from as little as just $15 one way including taxes, fees etc. and they have extensive routes too.
Have fun with the planning.

As for the cheapest airlines, keep in mind about the price PER bag which is NOT included. With the train, you could take night trains and u save from that night accomadations. I would buy train and it opens your ideas to planning. If you can, add Croatia and Budapest to your list.

As this is opening up for you slowly now.... As well as Croatia and Budapest, try looking at Romania and Bulgaria as well. Bulgaria is still one of the cheapest countries in the world - overall. Very beautiful too.
