First of all, I would call DPS and ask to talk to a tech and tell him/her what you said here. Voice your concern. IMHO what you have described is not enough to deny you a CHL BUT it is enough for a delay.
THEN, I would make every to get what's called a 'disposition' on your arrest. It's a report on your arrest and how it was handled through your release. You'll then want to send it to DPS to be added to your file. If whoever you talk to says they 'have no record' of your arrest, then get a signed and sealed declaration that the agency that handled your arrest has no record of it.
In addition, you'll want to get 'dispositions' from every law enforcement agency where ever you've been arrested, photographed and booked, in your entire lifetime. I know it will be a royal pain, but DPS will require all those dispositions to process your application.
Hope that helps. And if you have more questions, ask away! We are glad to help!
