What character special abilities are active outside battle? when do they activate (start working)?

for example "while this card remains in play.... blah blah blah"

Also, the ones that say "while this card remains in play" activate when they enter battle, and are ongoing for as long as that condition (being in play) is met.

That is correct.  Setting her aside takes her out of play, so the ability resolves and is no longer active.
