I have long curly hair and to most peoples surprise I have never owned a blow dryer in my 25 years! I use a mouse by Treseme (sp?) that is for curly hair and containes conditioner. It's not but a few dollars and totally worth it for me! I don't like hairspray or gel because it tends to dry out your hair.
For Shampoo and Conditioner, I use Panteen Pro V for curly hair. It helps hydrate your hair and has been the only stuff I could use over and over without have to change brands after finishing a bottle.
As for cuts, NEVER CUT BANGS! With curly hair you would have to straighten them every day or your daughter would end up pulling them back to get them out of her face. I suggest keeping her hair one length or cutting layers toward the ends but not short layers. Small layers at the bottom help with volume so if she has plenty then you may not want to do layers.
I have always gone to the cheap hair cut places (fantastic sams for example) and just had 1/2 an inch cut off the bottom to keep the ends healthy. I don't try to do the funky styles, etc... as that does not really work for curly hair.
Best of luck as I know it's not easy to handle. Your daughter will get to the point where she will want to do her hair and enjoy the curls.
