If Iname is your commander in a game of Commander, you may choose to put it in the command zone after it dies, but if you do, you won't be able to exile it. If you do exile it, you may put it into the command zone from exile after resolving its ability.
You can exile the card even if you choose no targets.
You may target Iname, Life Aspect. However, this doesn't do anything since the card will no longer be in your graveyard when the creature cards are returned to your hand.
