Ughh! yeah, I know the feeling, I know many times they don't do on porpuse but still.
I remember my daughter going through a short phase around that age, no sure if this is common or we are just the "lucky" ones, in my case it didn't last long and honestly I didn't even noticed when it pass, but she was her sweet self for a few years, now clothes to the 14 we are having it crawiling back.
Just last night I let her stay awake until she wanted, then today morning I wake her up to ask her for her jeans so I could wash them and she gave me the actitud! Really, after I let you sleep late and I am also watching your clothes and you give the actitud?! Grrrrrr!
In teh perfect world they would recognize AND show their appreciation on her own (without us asking for) but in my case I have to tell her "fake it until you feel it" (no sure if that is the way to say, lol.)
About the step dad, is hard. I married my husband when my daughter was little, and I didn't let him to discipline my daughter, which I think it was the right thing, however that at one point backfire me when years later he was still no discipline her and I was there alone, and of course when I say "hey, you have to" he said, "you told me not to", is being many years now from that and things now doesn't feel like step family any more, but it was hard to make the change and to decide how and all that, I don't really have an advice because I am not sure if my way was the best way, but I can tell you that the important is that he loves your kids, AND that your kids know that, all else it takes time to adjust and to find balance.
Oh, and there is also the old say of nobody knows what they have..., so perhaps one day you just become "so sick" and stop doing what you do for a week, maybe that would help too, wink, wink ;^)
