She looks like a Crystal! Good idea! or, since Pippin likes her so much, how about Merry (I know, in the movie, Merry is a boy, but it's really a girl's name).
Housebreaking: she may just not be used to your routine yet. With an older dog, routine is key in housebreaking - and reward/reprimand. They understand that much better than puppies. Just make sure you take her out at the same general time every day and wait 'til she goes potty before you bring her in. Praise, praise, praise immediately after she goes potty outside and reprimand immediately after she goes potty inside - if you're lucky enough to catch her in the act.
It shouldn't take long to get her back on track.
