Foxfire:
Sorry for the "late" reply, but the weekend after opening day of hunting season isn't the best time to catch me online.

From the info given, it sounds like you need:
1. Sights
2. Peep sight / kisser button / both
3. Arrows to match poundage / draw length

Optional:
1. Release / string loop
2. Stabilizer
3. String Silencer
4. Any other shock dampening stuff you want (Limb savers, etc)

Best bet is do as Flash suggests. Take it to a pro shop with her and have them help with initial setup of draw length, etc...

I would also recommend putting everything you want her to use on at once so you don't keep changing the configuration on her. That can get frustruating for new archers.

Hope this helps!
