-Get a good solid set of modern road bike wheels.

-If you can't get satisfaction with the brakes change them. The alloy rims and new pads will help though. Also be aware that modern canti's and V brakes are designed for 80mm pivot spacing, yours may be narrower which creates some issues.
-I had to add some shifting pins on the chainrings to get satisfactory front shifting. You could either do this or put on modern ones if they are available for that crank pcd.
How do you propose we stretch the stays out, without risking damaging the frame? Is there a particular reccommended method, or do I need to find a frambuilder?

Converting to cassette will be tough as I'd have to ditch the current drum brake which I was planning on keeping (although one reason for this was to avoid expanding the rear stays!)
