Harold, why do I get the feeling this is a loaded question?
#1 400.8(1) could be argued, and I agree with Tom on 400.8(5)
#2 BX or AC, if we are using the generic term BX and actually refering to AC, then the answer is YES. Now if these fixtures are above 8" it doesn't matter, 250.110(1),
and as far as 517.13(b)exc2 it doesn't seem to be a concern here. You could also look at 320.108
#3 I think 110.12 could apply, (maybe a stretch here too) but all 800 articles with the exception of 810 mentions tagging abandoned cables for future use.
