Help appreciated parsing these...
15a.Fall in warehouse (2,4) - GO DOWN (Fall)
Can't see where 'Warehouse' fits in.
50a Fancy woman losing note - it's a worry (6) - STRESS (Worry)
The only 'Fancy woman' I can think of is 'Seductress', but 'EDUC' can't be 'Note', so it must be something else.
5d. Old man with a lot of bottle (10) - METHUSELAH (Old man)
The reference to 'Bottle' is lost on me.
