Probing and Coolant
Probing is great! U can use it to measure interpolated bores, and adjust your D-comp to keep you in spec.(make sure your tech can read macros!!!)
Programmable coolant is a must!!!!! Unless you like reaching into the machine after most tool changes.
Probing is good too if you are running multiple machines, as you can run tool breakage detection to alert you when drils, and taps snap off, before yuo go and try to mill the HSS or Carbide, if you aren't around the machine.
HSM isn't just for molds and surfacing, as soon as you start ramping up feed rates this comes into play, otherwise you will start rounding corners. This effect can be quite extreme even on pricey Japanese machines. If you are gonna be pushing the 100ipm relm of feeds,(which you should be with an SS machine, I'd recommend it)
