Every courthouse has a law library. The local ones in Collin and Dallas have prove-up questions to finalize your divorce, and some counties have pro se (unrepresented) dockets where the judge will approve of your decree. You should make a trip to the courthouse if you are not going to hire a lawyer and ask the clerks where the law library is and inquire what the local procedures are for an unrepresented client in that district.
Getting divorced is not like getting married. The paperwork only gets you into court. You'll still need to set the matter for hearing and provide testimony to the Court. You're almost there. I would hire an attorney to help you get over the final hurdles.
