Hey Keylimekai,
I just wanted to throw another set of subjective conjecture at you about this decision. I do believe that both Rutgers and Arizona would be wonderful places for you to end up. If you are interested in folks like Robbins, Braun, and Kosek, I will throw some additional folks at you who might excite your poststructural nature-society ambitions:
Kevin St. Martin and Trevor Birkenholtz at Rutgers, Jody Emel and Dianne Rocheleau at Clark, Joel Wainwright at OSU, Joe Bryan at Colorado, Lucy Jarosz at Washington, Trevor Barnes and Karen Bakker at UBC, Wendy Wolford and John Pickles at UNC, and Cindi Katz at CUNY.
What rising_star says is true about funding being messed up at Berkeley and Arizona. Funding is also messed up at CUNY and while it has its big names, it is a seriously underfunded program and it has proven difficult for some to get through it with all the traveling out to remote campuses throughout the boroughs to do teaching jobs that you have to shank one another to get. The city is crazy expensive and everyone is way too busy for there to be a very strong collegial community there. I have also heard recently from two sources that Minnesota still suffers from some internal boloney that makes being a student there a drag. If anyone out there can refute that, please do because I don't want to be disparaging, but I don't want to encourage folks to go there if it's a hard place to be still. Kentucky does have this social theory component, but a lot of that was the baby of JP Jones and John Pickles who are at Arizona and UNC now, respectively. It might still have a lot to offer someone with your interests, but you'd have to look at who is there.
To attempt an answer at some of your other questions: No, you aren't aiming too high. Many of these programs have different rules for entering without a MA. CUNY says that they will accept you without one, but there is also the MA only program at Hunter and I am not sure what the crossover is there. Hunter does not seem to have any poststructuralist nature-society people though. Perhaps Marianna Pavlovskaya would be a good person to work with, but her interests do not seem to thoroughly cover nature-society stuff. And I am sure that the funding situation at Hunter is worse than at the CUNY Grad Center, so... Another question you had was whether or not going straight to a PhD program was advisable. I would say that some admissions committees might be skeptical of you being sure it is what you want to do for the next six years, so you might have to prove that. On a personal level, you might want to ask yourself that question and think about the MA programs that risingstar threw out. They would be a great way to make sure you're doing what you want while also making you more competitive when you apply again for PhDs. But even if you decide to do that and then end up in an MA program that also has a good PhD program, you might have a better chance at getting in and knowing what you want to do and who you want to work with.
Good luck
