First time in LX F - what to expect on JNB-LHR?

[pilot]

Hi,

I'm taking my first LX F-class flight in a couple of months from JNB-ZRH-LHR, and I was wondering what to expect on the ground? It seems like I'll get to use the Virgin Clubhouse which looks nice, but in particular I'd like to know:

Is there anything like curbside check-in?
Is there an escort through security, or fast-track?
Is there an escort from the lounge to the plane?
What kind of ground services are offered at ZRH during the connection?
Is there special baggage labelling besides the usual orange *A priority tag?

Thanks for any info or tips!
