      Well, since you've got thumbshifters, I'd first try switching to
      friction mode (the little lever on the side of the right shifter),
      which lets you trim cable length continuously, rather than "clicking"
      into gear...

      Some other things to check would be:

      * tightness of rear cassette (or freewheel) -- sometimes you need to
      add a 1mm spacer to get the cassette to lock down tighly on the hub.
      If there is any play in the cassette, resolve that first. Especially
      since you just switched cassettes -- it's very common for them to
      have slightly different widths, so the locknut engages before the
      cassette is clamped down.

      * straightness of the derailleur hanger. On your steel bike (sweet
      frame, BTW!!!), it's integrated into the frame, but can still become
      bent slightly. Good shops will have a Park tool to check alignment,
      or you can roughly eyeball it.

      * make sure the chain doesn't have any protruding rivets along its
      length -- especially since you have two chains attached to each
      other. (and make sure they're the same type of chain, and that you
      don't have a length of old chain attached to some new chain with less
      wear!)

      * the Park tools site has pretty good tips for adjusting your rear
      derailleur -- I assume you've gone through and set the H and L screws
      and the B screw (to adjust the angle of the derailleur body), but it
      never hurts to start over and get everything dialled in properly.
