Where should I start?

Usually with health insurance, because it is legally required and is often a precondition for registration or employment.

Do I need liability insurance?

It is not legally required, but it is very common in Germany. Some landlords ask about it when signing a tenancy agreement.

That depends on the responsible registration office and your documents. The eVB should be available before the appointment.
