In section "Change Relationship to Employee to ex after finalizing the Ben Admin event and generating Benefits enrollment forms", if the spouse or domestic partner is changing from current to ex, we typically make that change prior to finalizing the Ben Admin event and generating the benefits enrollment forms. How will this be affected if we process after finalizing?

You want to change the relationship to EE after the dependent's coverage period has ended. For example, even if the dependent became an ex mid month, the dependent still have coverage through the end of the month, and the relationship to EE value needs to remain as is until that coverage period is over, which is why we change the spouse to an ex using an effective date AFTER the coverage period has ended.
