Ken,
All of these can be saved in a single registration on the PSR-3000. However, if the vocal effects are to be triggered on and off during the song itself, this action cannot be saved. There has been some discussion at the PSR Tutorial about triggering vocal harmony in midi files, but nothing in the form of a lesson has come out of it at this time.
When saving midi information to a registration, press the Memory button, then place a check mark in the box net to Song.
Good Luck,
Gary
