I'm overweight and recently started back the gym. I used to be very active, lifted heavy etc. Right now I'm doing pyramid sets, compound moves hitting a major body part, followed by an isolation move but less sets as it's already pre-fatigued from the compound move, back with biceps, chest & tri's, legs followed by abs. Pretty standard as I'm getting back in to things.
I'm fitting them in to my lunch hour so rest is kept down 20-30 seconds and off again. I'm sticking with this for approx a month then changing it. I don't have much problem in adding bulk, it's shedding it that's my problem.
As adiemus has said, what are her goals?
As a P.T what programme would you design for someone looking to tone up? Which is pretty much what you're asking (as I read it).Is she looking for muscular definition or not? What kind of workouts does she enjoy? If she hates it she's not likely to stick with it.
She can get a good workout with the dance alone if you drill a move for long enough, ask anyone who does a lot of veil work how it targets the arms, shoulders/back

Core & back go hand in hand. camels/pops
Calves - for when walking on toes
Squats/lunges - shimmies
