Check out velo-orange.com for new old-style components. For 27" tires, try Panaracer Pasela Touring tires. I use them on my 1985 Santana and they work fine. For shifters, you could use non-indexed bar-ends which would be more comfortable than downtube shifters. The Santana is six speed and I have no problem with the non-indexed shifting. Almost any bike of that vintage would take Universal, Mafac, or other center-pull brakes which you should be able to find inexpensivly on Ebay.
Good Luck, I love the older stuff and have considered a similar project.
