A player, 5 March 2010
When I attack with Bayushi Miyoto and in my home Takuma->with attached flawless assasin and Suboru ; can i move before this battle resulation takuma and suboru to current battlefield or suboru current battlefield and takuma another battlefield ? (miyoto is bowed but in current battlefield).
and another question is attacked with nitsu. can i change location with takuma->with flawless assasin (takuma on my home)
used nitsu action ? or sogetsu .etc
reaction time is important for this ? active player or not. maybe ?

Yes, Flawless Assassin works as you described. After any of the movements in your examples, Flawless Assassin's Reaction is triggered and may be used to move its unit to any location.
Active player doesn't matter.
