looks like you take the eurostar to paris, transfer within paris from Gare du Nord to Gare de Bercy via the metro/RER or bus or taxi for an overnight train to Rome. For genoa, it looks like you would transfer trains again at Milan central station instead of continuing to Rome. relatively simple.
I've used the raileurope.com website in the past to plan my vacations within europe with minimal problems. The site allows you to see options for train service between many destinations; it is pretty much like a site like expedia or another airline site. I've bought my tickest online through the site with absolutely no problems, but you can also likely buy at the station. I've transferred many times within Paris between stations and it isn't that bad. You will not be the only one with luggage so no worries there.
I think that might be over to you to do some background work for your own holiday. The important question is do you want to go by train in order to see more of the countryside or because you are a train enthusiast? If the former. I would suggest you break the journey in Paris for a couple of days, then take a daylight service TGV to Milan, stay a night and finally the Eurostar Italia to Rome. This is a lot of rail travel. The night train is good if you just want to get there and sleep in a bunk on the train. Again, the question is what sort of experience are you looking for?
When all's said and done, there'll be more said than done.

Train is like planes for fares nowadays, yield management and all, so it can be very cheap to very expensive (especially the eurostar).
As for the night train from Paris, I took it lots of time since childhood, it's called Palatino, named after the Roman hill. Personally I stopped at Florence, but it goes to Rome. In 2nd class you're in a cabin with 6 berths, not for the claustrophobic. In summer it's quite hot, I wouldn't do it now. Here you have some info, I don't know if the prices are accurate : http://www.eurorailways.com/products/night_trains/paris_to_rome.htm

I have done London-Paris and Paris-Milan by train, albeit on separate occasions. The Eurostar (London-Paris) can be expensive, but if you book in advance and travel during off-peak times (say Saturday) you can do it relatively cheap. I've paid as little as GBP 79 for a R/T. I don't remember how much I paid for the overnight Paris-Milan train, since that was a few years ago, but it was also relatively cheap when booked in advance.

Just a note about raileurope, at least when it comes to prices in Germany, they are quite a bit more expensive than www.bahn.de. Before booking there, you should check for prices on the homepage of the actual operators of the train.

You should remember that train tickets in mainland Europe (including Eurostar) can be booked from 90 days in advance - book early to get the cheapest seats. Also, bear in mind that the laws of supply and demand also apply - don't expect to get super-cheap tickets at the busiest times (holiday periods etc).
In the UK, tickets go on sale around 12 weeks ahead, but this is nowhere near as rigid as the system in most of Europe.
