There is absolutely no rush to remove the offsets. I would wait a couple of months or more.
When you do remove them, draw an imaginary line in your head from the center of each offset to the center of the main rosette. You are going to cut along that line. Aim for a spot about half an inch in from the offset, meaning that the cutting will have about that much naked stem below the leaves. Usually you have to kind of spread or lift the leaves of the mother plant to see where you're cutting. I would use fine scissors, like nail scissors, which will fit better into narrow spaces.
