It's hard to generalize about wood shells, or pretty much any shell material for that matter. The drum's sound is affected so much by other variables (bearing edge, thickness, type/density of wood, etc.) that it's hard to pigeonhole wooden drums as having a particular kind of sound.
I tend to be pretty picky about my snare wires, but the Pearl S-022's are good and cheap. 20-strand sets are generally the norm and should work well on a late '60s Yamaha.
Vintagemore2000's suggestion for Remo coated Ambassadors is a good one. They're pretty much the definitive "classic" drum head when it comes to snare or tom batters. I have a slight preference for Evans G1's, which are Evans' closest equivalent, or Evans G Plus heads if you want something a little bit thicker. But any of these should serve you well.
I tend to like medium or thin heads on the resonant (bottom) side of toms. Clear or coated will have a slight difference in sound, but either will work. It's just a matter of preference. Remo Ambassador (medium) or Diplomat (thin), or Evans G1 (medium) or Resonant Glass (thin).
It might be harder to find consensus when it comes to bass drums. There are some very different tastes when it comes to bass drum sound. The Remo Powerstroke 3, Evans EMAD, and Aquarian Super-Kick batter heads all have their fans for a modern thump. All three of these have a built-in muffling ring. Some people like a more open, resonant bass sound and use unmuffled heads like Remo Ambassadors. Some vintage guys and old school jazz players go this route.
