To help get the shutter speed down if you don't have high speed sync use a polarizer and/or ND. Even with high speed sync I use a pol for outdoor portraits. I haven't figured out how to make color like that in Photoshop.
I can't remember where I saw it, Strobist.com or someplace, but there was a cool demonstration of a 3 flash set-up for bright light, outdoor portraits. There was a flash on each side of the subject set to normal exposure, and a flash on the camera set to -2 stops. The camera itself was set to -1 stop. So it slightly underexposes the background, and the on camera flash adds the fill. It was a slick look.
