Are you in Houston?
I checked usajobs and there aren't any specific openings. What they do have, however, is "open continuous" job openings. Normally an announcement stays on usajobs for two weeks. If you ever see any that are open for 6 months or a year, that means the hiring agency is keeping the job announcement open for an indefinite period of time.
Here is the search for Houston:
USAJOBS - Search
The key for federal resumes are the 'keywords'. Look at the responsibilities of the job announcement and put any relevant information in block paragraph form. Try to give specific examples for each responsibility if possible.
When you first apply you'll go to a self-assessment questionnaire portion. In this online questionnaire, mark yourself as a D or E. D is you have done the job independent without supervision. E is expert. For each question there is a score (1-5 with 5 (E) being the highest). Keep in mind, these questions may come up again in the interview.
I had a phone interview, and what I did was screen shot the questionnaire as I did it. I also wrote out answers to any potential questions that they may ask (even normal stuff like "tell me about yourself"). I'm not the greatest speaker in the world...in fact, I'm terrible at it. That method really helped me in phone interviews.
