Best rail ticketing option please, northwest Europe?

Hi all.
I would like to take a 4, 5 or 6 days round trip from Calais to Nordrhein-Westfalen following the journey pattern as detailed below. To your knowledge what is the best ticketing option to cover all this? For instance, is it good value to buy a separate ticket on each journey leg? (I’m 27 and travel partner is aged 34):
DAY 1
Calais Ville>Lille Flandres
Lille Europe>Bruxelles Midi
DAY 2
Bruxelles Luxembourg>Trier>Koblenz
DAY 3
Koblenz>Koln>Amsterdam
Amsterdam>Antwerpen Berchem
DAY 4
Antwerpen Centraal>Brussel Noord
Bruxelles Midi-Lille Europe
Lille Flandres-Calais Ville

I can recommend that you use the services of Rail-Europe and take their advice. If you live in the South-East, try to visit their head office in West Malling in Kent.
I have recently returned from travels in Central France, using SNCF Corail (Intercite) trains, and Rail-Europe booked all of the journeys and were meticulous in getting me the best deals.
Fortunately, I am not too far from West Malling, so was able to go there and received personal attention. I am very pleased with the service which I received.
Edit :-
You’re right about the Piccadilly office James, but the relocation was merely from a different part of Piccadilly. The head office is still in West Malling. Use whichever is more convenient to yourself, but at busy times you may have to wait at Piccadilly to speak to an agent.

Calais Lille one hour and thirty minutes

both probable an european citizen thus a interrail global pass

euro 393 for both persons

thus travel by hispeed is not needed
