The scan is conventional. Like Compressor Stall says, don’t bother about the N1 setting. With experience, you will get to know them roughly but personally I don’t use them when flying raw data. Your scan will be already very demanding at the beginning on the PFD; No time to waste looking at the Ecam upper display. I usually move the levers very gently one by one until I reach the target speed and the speed trend is gone. The speed trend is your best friend when flying with ATHR OFF. The more you will do the easier it will get. It’s not rocket science. I found it challenging at the beginning tho. But that’s probably because of lack of practice. For fine tunning, I sometimes look at the N1 values to match both engines.
