TrenItalia train pass versus Eurorail vs Buying as us go?

Question

I have several questions:

1) Is a Eurorail Pass and TrenItalia Pass the same thing?

2) Can I use a Eurorail/TrenItalia pass on all trains in Italy?

3) Can I use the pass from FCO airport to Rome Termini?

What is the diffference in amenities between 1st & 2nd class?

4) Is it worthwhile to reserve seats on trains between cities (I can do via the Internet)?

5) If I reserve seats do I still have to get my tickets stamp at the yellow booth/box ayt the station?

Here is my train itinerary for more info. What kind of Eurorail should I buy for this itinerary?

(FCO to Rome Termini, Rome to Naples Centrale),

(Naples Centrale to Pompeii and back, Naples to Rome),

(Rome to Florence),

(Florence to Pisa, Pisa to La Spezia),

(La Spezia to Genoa and back),

(La Specia to Genoa, Milan onto Venice ( 1 trip)),

(Venice to Rome),

(Rome termini to FCO airport)

All trips starting between brackets is on a different day.

Ant information will be appreciated.

Answer 2

I had a similar question and someone posted a great reply for it. Here is what he wrote...it'll be a great help!

http://www.trenitalia.com/en/index.html.... is the *official* site, with all the info you may need including last minute offers (and strikes :) and other news for travelers)

About trains: Locale, Diretto, Regionale stops in all cities and towns, are slow and are used for traveling in the neighborhood.

Interregionale (IR) the same but for longer routes (between two or three regions, generally).

Espresso (E) for very long routes inside the Country, low price.

InterCity (IC and IC plus) is faster, stops in main cities, costs a little more; EuroCity (EC) the same but international.

Eurostar (ES) is faster, stops in big cities only (Milan, Florence, Rome, etc), costs more and booking is mandatory.

Cisalpino (CIS) is Italian/Swiss; the best choice if you have to trip between Milan and Florence or Milan and Venice, since it's fast as a Eurostar but cost like an InterCity (it's an international train but you can use for traveling inside Italy, there's no limitations).

There are also Night trains: ICN-Intercity Notte, EN-Espresso Notte.

Booking are available for every train but mandatory only for Eurostar or sleeping cars or InterCity plus

It's just advisable for InterCity, Eurocity but HIGHLY advisable for Espresso and Nigh trains, if you want to be sure to find a seat; I know very well because of personal experience!

You can buy any ticket in advance or in the railway station or in some Travel Agency or from home; by choosing ticketless option you will receive a code you have to give to ticket inspector while on board.

For Eurostar, you can buy tickets till three hours after the train departure from the station it's originated from. Anyway you risk not finding seat, if you do so lately. If you book a ES and you can't use that train for some reason, you can ask for a "change of booking", with no further fee.

In Italy Trenitalia cover almost all the Country, Ferrovie Nord are useful if you plan to trip north of Milan (like Como province or nearby) http://www.fnmgroup.it/en/index.htm...

International train from and to Italy are listed on Trenitalia website, as well.
