You want to find a lawyer half an hour before your court appearance? You should have thought of this a long time ago.
Why would you want a lawyer for a speeding ticket? You go in, plead guilty, pay the fine, and move on with your life.
Texas is a "no retreat" state. An old court ruling from the 1800's establishes that a person is only required to retreat as far as the air against their back. You cannot shoot trespassers, however you can use deadly force against any person who is committing theft or criminal mischief (vandalism) on your property "at night", but only at night. This law was established to keep professional criminals from constantly avoiding arrest by using the cloak of darkness. Texas also has a strong insurance lobby. As far as entering your home, day or night you own them. It is rightfully presumed that by entering, or attempting to enter, your home they present a danger to yourself and your family. I have personally worked cases where citizens have exercised these rights and were never charged. These cases involved a doctor who walked out and exterminated a 16 year old boy who was stealing a battery out of his vehicle at about 3:00 AM. I also recall another where a man stepped out on the front balcony of his home at night, with a high powered rifle and killed one of the boys who had stopped with a group of boys to vandalize the vehicle owned by the man's son. Neither committed a crime under Texas law. Now not everyone considers it worth a human life to protect a car battery, but the law leaves it to the discretion of the property owner. Aside from normal juvenile pranks, career criminals know not to mess around someone else's property at night in Texas.
