On the 24" wheeled Peugeots that I build for my kids I used single front chainrings. I also fitted a modern Shimano rear derailleur that would index on a 6-speed freewheel. I then used a gripshift shifter on the handlebar - figuring that I wanted the kids to enjoy and use the bikes rather than get frustrated learning how to shift by friction. Both my son's and my daughter's bikes were set up as "roadsters" rather than "racers" with upright bars. With my daughter's bike, I even made the effort to change the top tube to a pair of laterals - effectively making it into a mixte frame.
Others on the list may be able to help you as well, but I think we may have some of the bits you are looking for at Bicycle Specialties. I'll have a look for you on Monday when I am back at work.
Cheers, Larry Strung
