a t34.48 starts boosting properly at about 1400rpm. a t34.63 was about 2500rpm. ive no idea what speed the shaft on the turbo would be spinning.

it was a few years ago now but i remember much prefering the stage 2 .48 as it was much more instant for accelerating from a standstill.

It should spin freely at idle

At tickover it is perfectly normal to be able to stop the turbo spinning by holding the shaft, just pressing on the end will stop it.
My T3/34.48 starts boost at around 1400/1500, and is full boost by about 2600, but mine is a T34 compressor wheel in a T3 housing machined out to size.
