Airbus procedure always call for setting TOGA after TO and OEI. Please check the nice video from TAP (available everywhere, e.g. on youtube), they are very close to Airbus procedures.
Of course every airline is free to use their own procedure, that's why every operator does it a bit differently.
I never added TOGA thrust but hey, if you think you need it, it's never wrong. Calculations are done without.
