We are flying the new SOP since a few months now and there are indeed several items that could be better, including the A/T (I still wait until lining-up) and the Set Flaps UP speed.
Other items are Landing Lights (the captain as PF may not touch the switches, hrrrrrr...!), starting the Engines (both pilots do this together...??), arming speedbrakes by the F/O while he is PF, also setting the Standby ALT by the F/O when he is flying, etc...
But there are also some improvements, such as low workload during taxi.
I have made a powerpoint briefing that you might find useful :
