I am in far northeast Dallas, but I work in the Irving area. I know a couple of Z-scalers in the "mid-cities" (Hurst-Euless-Bedford area) that are somewhat closer to Fort Worth. I'm not aware of any Z clubs in the area. We've talked about trying to scrape a few modules together to run at shows but so far no organization to that affect.
I'm in pretty much the same boat. Was in N for forever and was looking for a change...considered just getting out completely for a bit, but as I sold off N and had some funds I decided to move toward Z. While it's not a huge amount smaller, the difference was significant enough to me. I've been in Z about 4 years now, but exclusively for about a year or so.
Truthfully, online is about the best place to get answers/insight. But I'm always up for meeting MRR's in the area and also would be happy to help if you have specific things you are needing assistance with.
EDIT: I have a Facebook page that shows some of the stuff I've been doing in Z and my (lack of) layout progress. www.facebook.com/mockind
