A good starting point would be the CAA LASOR's:
Reference:LASORS
Title:LASORS 2008
Description:The LAS section brings together in one easily understandable book all the flight crew licensing information otherwise found in JAR-FCL, the UK ANO, AICs and the old CAPs 53/54. Regulations and procedures do change between the annual publishing of LASORS and these updates are notified by AICs and published on our website
Personnel Licensing | Safety Regulation. The ORS section is also by no means in its definitive format. If it can be enhanced to make the whole book more valuable to the pilot it will be. The aim is to give pilots a one-stop reference for all aspects of safe aeroplane operation.
2008 LASORS are available here:

Bed time reading?
Yours are quite particular questions but hopefully you find a few answers in the above. If not, give the CAA a call, they're more friendly and helpful than we like to give them credit for!
