I'd go for Torq myself.
Don't use/like wing bars but regarding the measurements the bar width should be based on your shoulder width as that's what you will naturally find most comfortable. You don't want to go too wide as riding on the hoods would be uncomfortable.
There was a link on the pez site to a little video about bars and chosing the right ones as an intro to a bike fitting dvd. It was quite good but seems to have disappeared now, I expect you could find it on youtube though.
