David - Process verification will be a major part of the audit as will product approval (incoming). Their expectations will run along the same lines as QS but don't expect them to even acknowledge a similarity.
They will have an audit plan and will ask you questions as they walk through it. Let your system speak for itself. You will be surprised how well it meets their requirements. If they do come up with anything, they will explain how it should fit in and give you plenty of time and help in implementing it.
Relax and enjoy the day.
