T.S.
There might be a co-parenting class offered in your area which would REALLY help with this. I took a class when my ex-husband and I first separated. He didn't take it with me, and never took it later (as he agreed to) but it was still very helpful for me learning some skills for dealing with just the kind of feelings you're having.
Anyway, try looking it up. Mine was offered through Kaiser, but they also offer them through family services etc.
As for the specific things your talking about here, I'd say just talk to your daughter and reinforce the values you are setting at home, but don't make it too big a deal and DON'T try to tell your ex and his new wife what to do. Unfortunately, unless he's showing her pornography, or teaching her to attack Santa impersonators, I don't think you should even bring these things up. These are personal parenting choices and you're just going to have to let him parent her his own way.
If you feel an issue absolutely MUST be dealt with, than make sure to frame it so that it's about your daughter and not about you trying to control their household ie "DD mentioned that the police came to your house and she was very upset about this. I think she'd feel safer if she didn't witness that. Maybe in future if you and step-mom are not going to be able to resolve your argument quickly, you can call me and I'll come and get DD so you don't have to worry about her."
