I've translating 「やってくれないかしら」 as Patchy wondering in third person, the omitted recipient in the sentence being Alice (魔理沙がアリスにやってくれる) rather than herself (私に)... not entirely sure, though, can someone confirm? Thanks.

What kinds of other things, Patchy?

I read that last line as "If they're going to sweet talk I wish they'd take it elsewhere".

Yes, that's a better translation than mine; replaced it.
