Guy, use the punch shot to get out of the deep rough or bunker, and pitch/chip shots from the light rough. Keep an eye on your lie percantage, it will determine what type of shot to use for diffrent lie types. Remeber this during your practice rounds.
When putting from the fringe, use the caddy's suggested putting scale, and don't hit a fringe putt with a scale less than 60 or you'll just whiff your shot. A 90 putting scale is ideal for most fringe putts.
