I just sold a nice f/r derailer on ebay of the shimano tri color... got $35 for the rear and $15 for the front... you will get less on craigslist... I find that very few people excluding my self buy just parts on craigslist. The crankset I sold I think I got $35 for as well. I didn't have bar end shifters but I've seen those go for between $25 and $40 depending on condition.
You best bet is to offer them for sale on the Bike forum classics and vintage forum for sale thread. Offer them for a little less than averge ebay prices and someone will probably buy them here and save the hassle of ebay.
