I don't exactly know what this Central Auditory Processing Disorder is, but i could well have it. I can tick all the boxes you listed except for the 'behavioural problems' one. I'm a relatively fast typist, but I also spend a lot of time fixing up my sentences and re-wording things. This may stem from my perfectionist tendancies, but i can identify with some of your problems.
I'm up to my second blood test in a week, so hopefully soon I shall find out what's wrong with me. By the looks of things, all my social problems may be a result of hormonal complications.
