Hi SS. Welcome from the Pacific NW.
The ears......
Just leave them. Years ago, our cropping vet taped the ears over the head while they healed.. Not much different than what your girl's ears are doing now. It was pretty common. We have also had ears that hang down freely until they are healed enough to begin posting. It is the actual posting of the ears, along with a suitable crop, that allows the ears to stand upright. All you need to do its to let them heal. scabbing is natural and an important part of healing. And scabs form best and work best when left alone. No picking, excessive cleaning or ointment application is needed or recommended.
Member greenkouki, who responded wrote a visual tutorial on posting that is frequently recommended here on Doberman Talk. It is excellent. You should take a look at it and come back with any questions. It is strongly suggest that owners post their own dog's ears. the are many advantages to this, and virtually no downsides. Folks here are very good at helping first time Dobe puppy owners with posting. There is a learning curve, but once one get's the hang of it is becomes very routing.
