Try to relax a bit... it's not really as complicated or horrible as it seems. You do need to do some paperwork, but there are a lot of resources to help you and the things you will need are pretty accessible. It is a necessary evil, but for the most part, I was just excited to get through each step of the process. I was a bit cautious about collecting stuff when I was on my spousal visa, but once I completed the Life in the UK test and got my ILR, I stopped worrying about things so much. I hope to afford my citizenship soon, but with a baby on the way, I have to put that off for now. Nothing good can come of thinking the UKBA is out to get you, it's just bureaucracy and there is always red tape no matter what you do these days. You can easily manage it.
Having said all of this, it is easy to be paranoid, stressed out and overly concerned prior to an international move. It's a huge deal and every little thing you have to do just piles up until your head is spinning. Once you get here, you will find that you can finally stop holding your breath and enjoy being with the one you love. It's so worth it. And for me, the first trip back felt strange - like a vacation, really - because the UK was my home. I looked forward to coming back and sleeping in my own bed and playing with our dog and everything. There are moments of homesickness, but I really think if you truly accept the fact that the UK is going to be your home and you aren't moving back to the US, then settling in becomes a lot easier. Good luck!
Oh, and stop worrying about your traffic violations. I'm sure they will just see what an honest person you are for listing them.
