Tf727 servo questions

Yes I understand that. Separate the low reverse servo question and the accumulator question.

Is full kit needed with this shift improver?
Is a blocking rod, a good mod while I’m in there?

What is needed is what you expect from the trans. The improver kit will help, but it will not provide the nice firm shifts that a kit like Fairbanks will. I always use the blocker rod.
