Afraid I dont have the 753 RTOM tables at home, I'll try to have a look next time i'm at work.
Service ceiling is 42000 - as 752, but dont expect to get there with pax on board. If you are doing canaries / greece from the UK, expect to start at FL330.
Off the top of my head typical Vref30 (with4 or 5 tons of gas still on and av. pax load youll have around 140 - 142 kts.
