Now I need to find good dual purpose pads...
You may want to search the forum for more info on that (it will make your head explode) or start a new thread. There are really no true good dual purpose pads. However, you have the benefit of a lighter car and a lower top speed due to the V6.
Any street pad with low dust will run into fade issues after a few aggressive laps. Brake ducting can delay that but may not eliminate it. It depends on how fast she drives it and her braking habits. Riding the brakes will kill pads, especially street pads, very quickly.
You can run a lower heat range track pad on the street but you will get more dust and perhaps noise while driving on the street. Depending on the pad, you may also get faster rotor wear while street driving. I know it sounds counter-intuitive but the way track pads work, they are rougher on rotors when they're cold.
If you can take the time to swap pads, at least the fronts, between track days then having separate street and separate track pads is the way to go. Several companies such as GLOC and Carbotech use a pad compound that is compatible between their street pads and track pads. That means you don't have to scuff the rotors and re-bed the pads when you swap them. However they are a bit expensive.
This is a good page to read:
We are asked this question multiple times a day and for good reason. There are several variables involved in choosing a proper brake compound. G-LOC offers 8 different Compounds in their product line...

As a lower cost alternative to try while your daughter learns during the first year, I would suggest PowerStop pads. They have a Z26 pad that is very nice for the street and is low dust. They have a corresponding TrackDay pad for the track. It produces a good amount of dust but it works REALLY well. I've used them for 3 seasons and they have slowed me down from 140mph down to 45-50 with no problem and no fade. You should have absolutely no problem with a V6. You can swap between the street and track pad with no problem. RockAuto has the best prices.
I would still recommend brake ducts
