Batman: Arkham City Catwoman DLC question

Do I have to manually switch between Batman and Catwoman to play her missions, or by downloading her pack, is she automatically fitted into the campaign? I ask becuase I did the first two parts of her story, which was breaking into Two-Face's place and then finding Poison Ivy, but since then I haven't played as her, and I'm about half way through the campaign as Batman now. So do I have to manually change to play Catwoman now, because it would be nice to do something else for a little while.

Also, really random side question that has nothing to do with the main topic of this thread, but some of you may know: would reading the Arkham Unhinged comics ruin any of the story for me? I doubt they would, but I just want to make sure in case I start reading them before I finish the game.

she has her own story, along with a small part in the main, i personally hate it when the game forces u to play as her, she sucks balls..

Meh, she's a nice change to play as every once in a while.

Anyway, she is fitted into the campaign when you have the DLC (the game will automatically switch to her). However there are locations you can go to where you can swap out Batman for Catwoman or vice versa.
