You declare which player, planeswalker, or battle the token is attacking as you put it onto the battlefield. It doesn’t have to be attacking the same player, planeswalker, or battle that Shaun is attacking.
Shaun, Father of Synths
Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any “as [this creature] enters the battlefield” or “[this creature] enters the battlefield with” abilities of the copied creature will also work.
Except for the noted exceptions, the token copies exactly what was printed on the original creature and nothing else (unless that creature is copying something else or is a token; see below). It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.
