If you don't mind driving a bit south of I-10, there's the American Shooting Center in George Bush Park - http://www.amshootcenters.com/. It's outdoors and therefore pretty warm this time of year, but the price and facilities are great. I'm sure others know of indoor ranges around as well; I've just never tried any in town myself.

And Carlson's got all you need for driving around with a handgun, for the most part. Keep it concealed and keep it with you in the car until you get your plastic, then keep it with you everywhere you can! And welcome!
