I went that route in February and suggest that whilst you need to have a reasonable level of knowledge - just as you would in the UK - such absolute precise location of the clauses is not likely to be tested.
I can only speak from my experience but my FR was conducted in a very friendly and helpful way, was very thorough, spending about 3 hours on the ground one day (including watching videos on airmanship, stall avoidance etc.) and an hour and a half in the air the next but mainly concentrated on the important bits like airspace, handling, pilotage etc.
I DID spend hours in the back of a BA 777 reading FAR/AIM 2007 but in reality a good guide to the FR stands you in much better stead.
Best of luck
