The differences between J and P don't come down to a messy desk, sorry to say.
What makes you J or P is whether the first judging function (T or F) in your stack is extroverted (Judger) or introverted (Perceiver). That's pretty much it.
That's only if you follow the cognitive function MBTI. Which is arguably very different from the dichotomy MBTI. There are some similarities, but if you want to go a bit deeper than a short description, they can't be said to be the same.
If you want to know about dichotomy MBTI, where you type someone on all four dichotomies and not with the help of functions, check out user reckful on the intj forum. He has very informatie posts. For example this one on the J/P difference.
Edit: He's more scientific accurate instead of giving a nice-to-read description, but that's what I personally prefer.
