DYKWIA beat me to it!
Lounge is fine, but not chauffeur.
Only in-person upgrades (at physical checkin, lounge, and onboard).
And, possibly, no WIFI as you need your EK membership linked, and EK were not allowing this for QF tickets.

Interesting that seat selection now works via QF website (it would still pay to make sure via the EK MMB). A decade ago one could select seats on QF, but it was decidely dodgy. Then it was disabled, but instructed to use EK. Now back to the orignial, it would seem.
