I have to buy a separate BA ticket from OSL to LHR to position us for the flights. With ample time between flights (my travel insc. will cover missed connections).

But will BA be able to merge the bookings and provide boardingpasses and check in all the way to HKG at our first point of BA flying?

I have already been on a AF a380, in Y main deck. Must say that its one of the quietest and most comfortable aircrafts ive ever been on.

Only thing was horrible AF service and IFE made it less enjoyable, combined with knowledge of a tight CDG transfer awaiting.
