Hey Dude, long time no speak. How are you?
For the BAOR there is a book called "The British Army in Germany: An Organizational History" by Graham Watson and Richard Rinaldi that may be of interest to you. It runs to around 160 pages and whilst I don't think it will answer all of your questions (for a start it doesn't give unit strengths), it does give very detailed Orbats for the BAOR (down to Battalion level or equivalent) at various points in its history, including which elements of the REME, RCT, RAOC (and then RLC) were part of the BAOR, which Division they were assigned to, etc.
I was able to get a copy online from waterstones a while ago for just over ten quid. You can get a free preview online here

If you're interested in the TA units you might want to check out this website, which has a fair amount of info:

If you ever find anything on the RMP please let me know!
Hope that helps
Cheers
