A few questions on hamsters. [Check inside].

We bought a hamster today, a Russian dwarf hamster to be precisely.
A few questions:
– Will she ever listen to her name?
– In case she will bite, will it hurt/will I be wounded?
– Who was it that thought it a good idea to let hamsters walk senseless walks in a hamster wheel or is there a wildlife equivalent where they show the same behavior?
– We already named her Anuschka, but if you can give us a name that wows us, we willl consider a change!
