I agree: start with fewer reps, heavier weights to build more of a muscle base ('toned' and 'sculpted' are just words used by advertisers who think women are afraid of muscle, but 'muslce' is what 'toning' and 'shaping' is built on). And don't worry too much about trying to lose any weight during this time...fuel the muscles with the calories they need without going overboard. Do this for 2-3 weeks, then change to a higher-rep, moderate weight workout to help get rid of excess fat over the muscle while maintaining the muscle(Jari Love and Tony Horton make circuit-type weight workouts that are more efficient at burning calories than straight-set work).
And as Debbie said: diet (as in eating food that nourishes your body)is a big part of it. Burn more calories than you take in to reduce body fat, especially during the second stage of your 'rotation.'
