im going to have to offer a different suggestion.....
deadlifts deadlifts and deadlifts.
Without having basically perfect form on squats/lunges(ie; a$$ to the grass) its really hard to fire your glutes correctly and you may end up having your quads do so much of the work. Women physiologically tend to be very quad dominant due to the increase "Q" angle of our pelvic tilt.
Balancing with deadlifts, and other similar exercises is definitely going to make a huge difference-- regular deadlifts, stiff-legged Deadlifts, SINGLE LEG DEADLIFTS (AWESOME FOR QUAD AND CORE WORK), glute/ham raises, good mornings. In all of these exercises you need to focus on initiating the "pull" from your hamstrings, not your back or hips
Also squats/lunges/step ups, etc
