If you exclude the non transgender issues with NJ (taxes, population and insert your favorite NJ joke here), NJ is very good with transgender issues. Most of my resource I utilize are in Manhattan (Callen-Lorde) but my therapist is in NJ and I could easily get other things needed here. Also surprisingly it's a little cheaper to use sources in Manhattan than in NJ, but it's cheaper to live in NJ.
As far as rights go, in NJ we are fully protected against discrimination for employment and housing (public or private). There are also hate laws in effect that help us as well and this is all state wide. Gay marriage is legal (if that applies) and people here are very accepting compared to TN where I lived prior to NJ. (I've been in NJ for 15 years now.) The closer to Manhattan the better, but even in the less populated Southern NJ there are resources just across the water in Philly and in other areas in NJ.
