Does this card's effect also prevent me from using Option card effects to play Digimon?
Yes. Option card effects are effects just like any other, so you can't use them to play Digimon.

If this Digimon is in play, can I activate effects that reduce play costs?
Yes. Effects that only reduce play costs can still be activated. Effects that reduce play costs AND play Digimon can’t be activated.
