You have to know that upon landing,the control law of the 'Bus reverts to that of of a classical airplane,therefore you could land it using whatever technique you like;sideslip upwind wing down,crabbing...no decrabbing...
Your instructors will teach you THE airline recommended procedure.I suggest you listen to them.
Just be aware that the control response is faster than your 737,but it's again a question of adaptation.
The only discomfort I felt qualifying on the 320 was a feeling of...er...nakedness!,without the big Boeing column in front of me.
It took about a month to pass...
Enjoy your new toy!
