Good advice from LipOut on the shaft front. At the end of the day there is no substitute for a little experimentation to find exactly what you like. Luckily old clubs are pretty cheap on ebay so buying and selling on is not too difficult. Though some of us find the buying part easier than the selling 
see picture!
I think the consensus is you won’t go too far wrong with any Wilson Dynapower iron from the late 50’s to early 70’s (1959 and 1962 Turfriders are my favourites) or many of the Hogan blades through to the 80’s. Plenty of good MacGregor blades as well of course. But thats just the start and you u can see all sorts of wondrous purchases made by forum users in this thread:

Lags collection would also be a good starting point - see http://www.flickr.com/photos/27786708@N02/2802670484/ or you very welcome to beg, borrow, steel from my ever growing haul. Mrs Arnie would thank you! 
Similar with persimmons I guess you would get lots of votes for early 50’s Macs (M85’s etc), Toney Pennas, Harry Bussons and so on. I have lots of these if you want to take a look, have a hit to find out what you like.
I have played vintage clubs with both modern and vintage steel shafts. Nothing to be scared of either way as long as you are prudent re: condition, sometimes a little luck involved as well 
Cheers, Arnie
