I made a very similar switch from a 46-36-26 Sugino to a 42-26 White Industries VBC, both with an 11-34 9 speed cassette. It's been a great move – I don't miss the few high gears I lost, I still have plenty of really low gears for loaded climbing, and shifting is a bit simpler. The bottom bracket spindle length with the Sugino triple was 118mm long, and the White Industries support docs suggested a 113mm length was ideal for that crankset so I swapped those out, although the dark art of chainlines is a bit of a mystery to me so I don't know if keeping the 118mm would have had any adverse effects. I kept the front triple derailleur which worked fine with friction shifting after adjusting the limit screws. I've since moved to a 10 speed 11-34 cassette just because it was what I could find when I needed to replace it late last year, but everything still works flawlessly.
