I have a similar series of decisions to make. I am waiting for the arrival of a 1969 Hetchins VadeMecum Mk 2 frame I just purchased. I'm excited about it and will likely go the easy route of mostly Campy, but we'll see....
As for your questions:
1) Suntour Bar cons go back at least as far as 1973. I pulled some from a 1973 Sekine to put on my Jack Taylor when I built it in 1974. 2) Shimano offered their bar cons with their first generation Dura Ace in 1973. See the 1974 catalog on Mark Bulgier's site: http://bulgier.net/pics/bike/Catalogs/Dura-Ace-74/ 3) I also put a Crane rear on my 1974 JT and road it that way for more than 25 years without any problems. A fine derailleur. I'm about to restore my 1975 Colin Laing with a Crane.
So all the above (as well as many others) are good.
Hmm, I can see I've been no help at all in narrowing your choices!
