Hi and welcome to you and Lucy Lu. Hope we get to meet her soon.
As for bows, if her hair is still thin on top, I wouldn't put any rubber bands in it till she's older. Get those little teeth like clips instead.
As for treats, you don't need to give her treats when she goes potty outside. Just start praising her when she's almost finished by saying "good potty" in a sweet voice. For something to chew on, buy 1/2" thick beef femur bones for her to chew on. Ask the butcher to cut them for you.
She can be given a bath. Just make it quick and simple, not scaring her. Keep your face by hers and talk softly to her and give her a kiss now and then while bathing her. Quicky wrap her in a towel and not let her get cold. This is also a good time to get her used to hearing a hair dryer. I would wrap mine in a towel then just blow the warm air into the towel so they would stay warm while getting dry.
