Enthusiastic "Re-Beginner"
I just plunge my arm in and plant plants, have never particularly needed to take out any water although I could see doing that for planting a lot of small stuff perhaps. Trim the tips off the roots and make a deep hole, bring the substrate back around the plant and then gently raise the plant so that the crown is barely above the substrate line. This pulls the roots upward a little, helping them point downward more. If your new plants cover less than 50% of the total substrate area then its unlikely they'll have an effect on the readings you're taking for the fishless cycle. (When plants -do- have an effect, what they do is lower the ammonia and nitrate readings potentially, sometimes leading you to false assumptions about how much is being accomplished by the bacteria you are trying to grow in the filter.)
