Pensions and ARF's are kept separate, so both you and your wife will have to set up AMRF's. After the tax free lump sum and the AMRF is set up, this will leave your wife with a very small ARF of circa €11,500. It may be an idea for her to run down the value of this to maximise the tax relief available to her. She will also be able to take 4% from the AMRF if she wishes.
Regarding withdrawals from the ARF, you both have to take a minimum of 4% from the ARF each year or if you don't, the Revenue will take the tax due on that 4% anyway, so you should both take the minimum from that.
As I said previously, you should look at running down the value of the €11,500 from your wife's ARF and just leave her with an AMRF.
