Dear rudderat,
Of course if your airbus tells you to switch off the fds,by all means do it, it is not the case for my aircraft type, the 737.
Concerning the 3000feet, i found it in a report where it was mentioned that most RAs occur below fl 290 and 90 percent of them(from graph view) occurred around 3000feet.
They mentioned reduced rate of climb to 1500 feet to avoid unnecessary RAs trigger.
May have been in the UK CAA website.
Concerning continuing the turn or not I would level the wings,better performance to follow the RA /if your turn happen to get you closer to the conflict traffic the RA will have to continuously recalculate the rate of descent/climb..and for reasons mentionned in the euro control link i posted above.
