Can't help with the SF-340, but for the ATR-72:

>- climb speed

170-190 IAS

>- holding speed

Around 180 kts but very dependant on weight and flight conditions (icing
/ non-icing). Normal technique is to set a fuel flow and then monitor
speed, increasing power or selecting flaps if speed decays too much.

>- Vref / approach / threshold speed

Again, highly weight and flight conditions dependant. I'll mail you some
data in a few days after I'm next at work.

Correct. True Air Speed is the term you're looking for.

No problem.
