I just recently moved to Houston Too, and i do agree Houston is to reliable on automobiles. But anyways, besides that, try going to the suburbs. Of course depending if you have children or not, Katy ISD in Katy ( Suburb of Houston) was just recently ranked in the top 17 % of all school districts in the nation.

I myself live in katy, here are some great subdivisions:
Cinco Ranch : www.cincoranch.com
Seven Meadows : http://sevenmeadows.com/
Grand Lakes : http://www.grandlakes.com/
There are also other subdivisions right next to these like: Falcon Ranch, Parkway Oaks, Katy Creek Ranch.
Good Luck, and welcome to Houston.
