Can I also use this card's inherited effect to switch the attack target to an unsuspended [Eosmon]?
Yes, you can.

If both players don't play a Tamer for this card's [On Play] [When Digivolving] effect, do I still perform <De-Digivolve 1> nocategory of your opponent's Digimon. (Trash the top card. You can't trash past level 3 cards.)?
Yes, you do. You perform the part of the effect after "then" regardless of whether or not a Tamer was played.
