The Nursing Mother's Companion is a really helpful book, especially if she's not getting BF support from her family. Otherwise, breast milk storage bags, the sterilizing bags for the microwave, and an extra set of accessories might be nice.
I didn't use a hands-free bra. Just wore my regular nursing bra to work and used hair ties to hook the pump horns onto my nursing clips until the suction got going. Cheap and easy!
