Thanks again, a quick update on what I decided to do. As I read the application again, I realized it didn't just say criminal convictions but said criminal and civil convictions. That seemed to me that I did have to include civil things like parking tickets, so I did for the one ticket I had rightly earned and paid for.
I wasn't as sure on the pending convictions line though. It only said pending criminal convictions that haven't been tried in court and was with the list of questions like "are you a terrorist?" that didn't feel right to answer "yes" to for a silly parking ticket I'm contesting. In the end on that one, I chose to mark "no" but scribbled under to see the notes section after the question. In that box I explained that I believed it was a civil, not criminal, matter, but that I had a parking ticket I was contesting in court as I had a permit to park in the area, but I was listing it in the interest of full disclosure still. I can't imagine it should create any problems, but I didn't want to take any chances with being labelled as deceiving the Home Office.
DH thinks I'm being obsessive about figuring all this out, but I want to make sure it's all done correctly. Wish me luck. I hate how long I'm going to have to wait now. At least I have the consolation of knowing that even if I had my passport, I couldn't fly since I'm in my last trimester of pregnancy!
