With my previous two T's, I didn't plan sessions, but I also didn't trust them very much, and I don't think I made much progress.

With my current T, I do tend to go in to my sessions with an agenda in mind. I usually have a primary topic I want to discuss, and if there's time, a few others that I'd like to touch on. We always start with what I want to talk about, and the session seems to flow from there. My T usually asks me to give her a high level of what I want to talk about before we start, so that she can make sure we at least touch on the things I'm concerned about.

Occasionally, I will either not have a plan, or know what I want to talk about, but not how to start. I will tell my T that I'm not sure what I want to talk about and ask her to guide me...she does. Or I'll tell her I want to talk about xxxx but I'm not sure how to start, and I'l ask her to ask me questions or guide me and she will.
