AuntPetunia... they absolutely make a insert to "WSD" your brakes! I have them on my bike! Go to or call a couple LBS... maybe a high end shop and explain the problem... my LBS fixed it for free for me... took 'em all of 5 minutes and completely made a difference to me in my feeling safe on the road.

I ride a mens frame so it had the mens levers... a WSD bike should have WSD levers on it... that is certainly something the manufacturer should take care of...

as to the shoulder pain... yep, kinda normal if it's just achy... be sure you are holding your uppper body up with your core muscles and NOT leaning on your arms to support your body... you should have your hands on your handlebars lightly... that should help a little... and also drplasma is right on about the width of the handlebar... it's a common change as everyone is built differently and the builders just guestimate what size will work for the frame size...
