Did the divorce take place or not, and is the waiting period (iddah) obligatory for a woman who was divorced by her husband before consummation, but he kissed her?

The divorce mentioned is effective, as divorcing a menstruating woman with whom consummation has not occurred is not forbidden. As long as the husband has not consummated the marriage with the woman, nor had a valid seclusion with her, she is not required to observe an iddah (waiting period) and is permitted to marry another man. It is advised to beware of obsessive doubts (waswasah).
