Do I have to list all my stuff in bankruptcy?
Yes. All the property you own, in the broaest sense of the word, has to be listed in your case. Everything. There's no legal way to pick and choose. Trying to do so could be a crime.
Do not jump to the conclusion that you will lose property you list! Listing everything correctly is part of th process of keeping your property -- not the start of losing it.
Most people filing bankruptcy keep everything they want to keep and can afford to keep paying for, if they owe a debt on it.
Let us repeat that: Everything is listed in your case in order to help you keep it. Here's an example of what can happen if you do it wrong.
